Two earthquakes with a magnitude of 7.6 and 7.8 occurred in Turkey. damage and deaths are too many tens of thousands of injured and thousands of deaths . @TheActionLab please help Turkey. The state is very inadequate in this regard.
Lol never thought I would see Manscaped as a sponsor here 😂
What happens if you break a capsule of water in to Cesium?
And i want to see what happens if the water and sodium are both liquid.
First liquid sodium into water then water into sodium.
u need to make a bullet with it (frozen), and then shoot the water, air gun obviously )))
You have a good enough beard and ponytail to advertise a manscaping product, but you need to figure out a way to collect audio without having that lav mic pull your t-shirt halfway down your chest. That sloppy neckline sabotages your video.
After we observed the sodium reaction in high school, I always wanted to get my hands on some cesium, learning that it is even more reactive. So while the result was a tad underwhelming, this satisfies something I’ve wanted to see for 20 years. Thank you!!
just because caesium is more reactive than sodium ( unless u heat it to around 600 c), it doesnt mean the reaction is more energetic, thats why its pretty underwhelming. cody’s lab has explained this in the video where he made the 1mil play button out of caesium
also im a hobbyist not a chemist, pls do correct me if im wrong
@@tomasbalnionis1399 Not correcting you but, I have heard that Caesium does indeed have a more violent reaction if you were to liquify it enough/heat it up, not sure where I got this from, but I hope someone tries it(ofc with a safe distance)
But after seeing this I'm not entirely sure anymore.
Not quite as exciting as hoped for, but still quite a fascinating reaction.
You literally have over a decade of clips on RUclips.
If you want something more along the lines of what you expected, look up “caesium fluorine reaction”
So, Caesium is more reactive than sodium, but sodium is "just right"
Kinda like ur mom when u don't clean ur room
Sodium and potassium.
If one reaction is too fast it doesn't make as an effective explosion.
😂
Goldy locks
At US$80.00 a gram I also want nothing to do with it.
Goldilocks tried the Lithium reaction, but it was too slow.
Next she tried the Cesium reaction, but it was too fast!
Finally, she tried the Sodium reaction, and it was just right.
Pick it up.
Goldilocks tried to sleep in the Copper bed, but it was too cold.
Next she tried to sleep in the Plutonium bed, but it was too radioactive.
The end.

Please do a collaboration with the slow-mo guys with this underwater reaction. That would be so cool to see in super super slow motion.
There is a video like that somewhere, but I don't remember wich channel.
It was very spectaculair. As soon as the metal touched the water, it formed many 'jets of electrons'. They wanted to leave the metal so bad that it ripped the sample apart in a microsecond or so. It finally made me understand how a large sample of metal could explode so fast, like before all the atoms had time to touch water molecules.
It really was one of the most spectacular chemistry videos I've ever seen!
If I van find the video, I will update this comment for you.
You wanna fly to London with a vile of Cesium?
@@DrDeuteron lol I'm sure they have people to find it there 🤣🤪🤘
Pause the video, top right corner is a cog symbol, when you press that there'll be a menu, select playback speed and you can slow the video to 0.25%.
Now that the cesium hydroxide is in your water tank, would it be possible to get the cesium metal back?
Likely possible, with a technique like electrolysis
Definitely possible
What do you think this is, Cody's Lab???
Recovering the cesium is possible and worthwhile, and required by law in most places since one is not allowed to dispose of cesium down the drain. Since almost all cesium salts are soluble, it's probably easiest to evaporate off the water (any combination of heat and vacuum) and collect the salt that remains. It might be best to start by neutralizing by bubbling in plenty of carbon dioxide, and then collect the dry carbonate salt. A less convenient way to neutralize is with a mineral acid and collect the salt (chloride, sulfate, nitrate, phosphate etc depending on the acid used). The advantage of using CO2 is that one does not need to use an exact quantity of it since it will leave no residue when evaporated. Once the salt is collected, it can be sold or passed to specialist labs that extract the metal, which, in the case of cesium, is almost impossible in a conventional lab without special equipment

I was going to watch the whole video but i saw the comment 😐

He was going to do it but his wife was against it.
It would be very stupid to do this in uncontrolled conditions. Cesium is extremely dangerous.

When I saw the cesium reaction my first thought was "This is a job for the slow-mo guys!" Nice vid, subbed
We live in a universe where anything can happen, including but not limited to Manscape purchasing Cesium at a higher cost than gold per gram for this man.
Fun fact: very pure Cesium actually has a melting point slightly above room temperature, but most samples have just enough impurities to lower the melting point (kind of how salt lowers the melting point of water ice). Don't feel bad if your sample is liquid at room temp though, it's very difficult to pull off unless you specialize in this.
I was wondering why bromine and mercury were the only elements considered a liquid but this explains that. Thanks!
Maybe he has a very warm room
Studio lights and handling also can make things very warm.
@@yummyjackalmeat I guess he hasn't gone to energy saving LED lights yet but I am sure the revenue from his channel more than pays the huge electric bill for those halogens. I am very curious how one can order a dangerous chemical for home delivery.
What is “room temperature?”
Minor correction, Cesium is the most reactive, Francium is less reactive due to relativistic effects. 0:16
Nerd 🤓🤓
What are the relativistic effects you mention?
@@deusexaethera The very strong positive charge of heavy nuclei (Francium has 87 protons) results in electrons being pulled very close to the nucleus as compared to lighter elements (hence more Coulombic attractive force). Another effect of electrons being pulled in that closely results in the electrons moving at speeds close to the speed of light and becoming heavier than expected due to relativistic mass expansion. The combination of more Coulombic attraction and heavier electrons means the outer shell electron of Francium has a higher ionization energy than expected.
@@deusexaetherabecause francium is a heavier element, it’s more positively charged for its size compared to elements like cesium or potassium. So it holds its electrons tighter which means more velocity, which at those speeds on those scales basically creates mass, or at least pseudo-mass. This makes it harder for it to be attracted to a different nucleus. Cesium is actually right up at the limit before this effect takes place
@@cyntrixta1884why the hell are you here on this channel then, nerd?
Pronounced "Fran-see-um", I believe?
Because France and not Frank ye. :D
And jojoba is pronounced with a Spanish _j_
And also less reactive than cesium.
Who cares 😂

One of the greatest and most memorable experiences of my life was given to me by an educator. I'll be vague as he isn't dead yet. He was very creative in his methods. He introduced a handful of us to the reactivity of sodium by chucking a large block of it into a small body of water. It exploded quite a few times. The chunk didn't come apart for a bit and the explosions were enough to heave it out of the water while it was still one piece. I chose "heave" on purpose as it was more of a riding the wave scenario, but it would leave the surface of the water and travel a bit. They would put him in jail today, but I retained everything he ever tried to teach me.
This is an excellent presentation.
Thanks. In my high school days, we'd wait for a heavy thunderstorm at night. We'd put a cherry-size chunk of potassium in the pocket of our homemade wrist-rocket-type slingshots and shoot it through the heavy rain. The potassium had enough mineral oil on it so that nothing happened when airborne, but when it landed a block away on the wet street, it would explode with light, and sparks, and a lot of white smoke. The neighbors didn't have a clue to what happened. But yes, potassium was our favorite. But we also liked sodium.
I would like to say that it is partially because larger amounts of Sodium and Potassium can typically be used that they sometimes get bigger reactions. Cesium is expensive, and using more than a small amount Cesium is often very difficult.
he said that
I work in the Oil and Gas industry; when drilling extremely high-pressure formations, we use Cesium Formate as the drilling mud to counter the pressures. My question is, how is the Cesium stabilized? An interesting fact about the Cesium Formate is that you can't buy it; you must rent it. For offshore jobs, a boat pulls alongside and delivers it to the rig. The ship stays until the job is done, and you must pump it back to the ship. As you can imagine, it is a costly operation. Rough numbers - Gulf of Mexico Sea Water is about 9 pounds per gallon. Cesium Formate is in the 20 pounds per gallon range.
Cesium is even more reactive than francium. Due to the size of the francium atom, relativistic effects already arise in the electron shell there, which reduce reactivity.
Not many people know that.
You should qualify it by saying "Cesium would be more reactive than Francium... " as Francium can never be collected in enough quantities to study its chemical nature, as any visible samples would instantly vaporize because of its high radioactivity and low half-life. What you quote is theoretical prediction.
Bob: imma eat banana
Me: NOOO!!!
Bob: explodes*
What happens when you put Cesium in a pool, letting the fragments hit the water again?
I imagine it'd be pretty crackly
The epa shows up 😂
Fireworks party
There is a video on chucking sodium into a lake which is so funny because the ejected fragments falls back into the water again
I was going to say the same thing!
Thank you for explaining that it's actually a Coulomb explosion rather than a hydrogen explosion like most people think. If anyone needs Sodium metal, I sell it and have tons. I also have several videos on my channel showing everything below Rubidium in the alkali metals group exploding in water. We even blow up fish tanks with Sodium on a regular basis. Lmao! One thing he doesn't mention is that the majority of costs on Sodium orders goes towards packaging and shipping due to it having to be shipped a special way due to its dangerous reactivity. Any seller who ships it without at least 2-3 layers of protective layers of containment such as sealed bags and a lot of bubble wrap and a strong container that sits dead in the middle of the packaging. It must contain any and all leaks and render any spills harmless. Most sellers don't do most of this and refuse to ship properly, endangering customers and shipping service employees. I can guarantee you that no eBay seller besides me ships it correctly. Not going to write out names, but we all know who they are. That's the only reason they can be cheaper than me as we operate on paper thin margins after donating our profits and a LOT of chemicals and elements to help struggling science and chemistry based RUclips channels make better and better videos.
I had a nice sealed glass ampule with a few grams of mercury that broke. So now I have it in a flask with a stopper. If you are able to reseal it in a glass ampule like he had his cesium in, I’d love to talk. Much safer I feel for display purposes than a flask where someone could just pull the stopper.
"What's your favourite metal?" is a question I never thought that could be asked.

I lost your channel for so long glad i found it again. I love watching these with my daughter
I heard that "frankium" (as James calls it lol 😂😂) would actually be less reactive than cesium due to relativistic effects.
lol I was screaming it's france-ium!
Francium, from the famous European country Frank.
@@Axman6 No, from the country which was once part of the Frankish Empire and is still called Frankreich in German (and similar in related languages).
In Classical Latin the c would be pronounced "k", but in Late Latin it would be "ch", as in modern Italian.
Glad to see the coulombic explosion explanation is spreading.
I would say the way Cesium reacts with the water comes from it having a low enough melting point to get an instant explosion in a room temperature experiment, unlike Sodium and Potassium which need to melt first (NaK shows the ability for instant explosion probably due to its liquid state at room temp).
Being a liquid reduces the interference from surface oxides as they slough off, and also permits the surface to change as is necessary for the coulombic explosion. Seems like the gas layer created by sodium and potassium delays the explosion which is why you can see them melt before exploding.
Is it just me or have your experiments been way more intense lately? 😂 Not complaining haha
0:17 I think this part was phrased very poorly. The reason there are no weighable samples of francium is not the 22 minute half life of 223Fr. This is a fair amount of time and would easily allow us to study it in detail. The problem is that there are no efficient decay chains to produce it, since during the alpha decay of 227Ac only 1,38% of the decay products are 223Fr. Together with the long half life of 227Ac (21,7 years) no meaningful amounts of 223Fr can be seperated. Oxygen15 for example has only a 2 minute half life but has medical uses and can be generated in a cyclotron.
Cesium is NOT liquid at room temperature, its melting point is at 28 degrees celsius and 0:06 is plain wrong. There are only 2 elements which are liquid at room temperature: mercury and bromine.
I really want to see potassium explode underwater as you said potassium is just right for an explosion so it would be pretty cool.
At that price , the caesium reaction isn't so much disappointing as heartbreaking.
I'm from Goiânia and i just saw Cesium and i knew u had the deal
Thanks for uploading!👍❤️❤️
Wow! It is surprisingly underwhelming! However afterwards you can piece together why.
Can you talk about the Beirut ammonium nitrate explosion? I just was looking at videos, and I was really curious about how this happened.
ammonium nitrate which is a fertilizer went kaboom
Great suggestion, especially for an eye witness of what happened that day like myself but basically you only need 2 main ingredients to make any compound blow this way which they are corrupt government officials and stupidity all at once!
@@daizdamien1409 Sorry, I meant more like what causes the explosion on a chemical level/storage procedure for volatile chemicals/tannerite... There's lots of interesting stuff you could delve into around the topic...
@@waelfadlallah8939 Wow! Sounds/looks terrifying! But also very interesting! But also very sad!
@@vagabondcaleb8915 appreciated! And worth noting that after 4 years of that blast, people are still recovering and the intresting fact that only a fraction of the ammonium nitrate exploded while the other portion is just blown away. It was classified as the second most powerful explosion in history leaving an entire city damaged and affected on a different levels.
was it safe to touch cesium like that?
I guess the most common isotope of Caesium is not radioactive, which must be the case of the vial. Isotopes 135 and 137 are very radioactive, Cs-137 caused a major accident in my country (Brazil) because of misinformation and curiosity together with lack of disposal control of an X-ray capsule that was dismantled and Caesium salt (which glows bright blue in the dark) was used to play with, basically. In that case was not safe to touch, neither to be near it.
Francium is actually less reactive than cesium…
I recommend to verify these statements with a sodium-potassium alloy (NaK) it's fairly easy to make, it's liquid in room temperature, and to my knowledge it's the king of Alkaline Reactivity. Not saying it's wrong but as once Thunderf00t shown it's not the whole story. Just if you are about to do it - take very small sample and double on safety.
I was sad for this nice caesium vial, but I read here you may be able to get some of it back. Looking forward to a followup.
Fun Trivial Fact: Older android phones (like Android 5 or 6) had one of their alarm ringtone named as 'Cesium', and it is just as life threatening as iPhone's Alarm ringtone
never really "got" chemestry when I was in school, but through your videos explaining the little picture it's making a lot more sense.... wouldve been really helpful about 45 years earlier...cheers
I learned more about Manscaped than about cesium from this video.
0:16 I feel it’s worth noting that Francium is actually less reactive than Cesium due to relativistic effects on the electrons found in sufficiently large atoms
The more you know... thx
@@u1zha No problem c:
This is amazing! Perfect demo!
francium (if you could get some) actually is less reactive than cesium due to quantum effects. It's been a couple years since if've taken quantum chemistry, so i'm not exactly sure why (we didn't study that specifically) but super-heavey elements are less likely to exhibit the same trends as the stable ones in their periodic group. for example Oganesson is predicted to be a solid even the it is in the group of "noble gas"
The reason the hydrogen doesn’t burn isn’t due to a lack of flame or heat as per 2:01, it’s due to a lack of oxygen. The reaction between caesium and water produces a ton of heat.
Curiously I have experience with Cesium under supercritical temperature and pressure in an autoclave with a sapphire rod window. The aim was to measure the reflectance of this metal under extreme circumstances. The optical measurement was through the sapphire window which usually is very resilient. However, cesium completely destroyed the sapphire window within seconds - super aggressive! So we still do not know the optical properties of cesium under supercritical conditions.
That's an awesome story! Pretty terrifying too. Never underestimate the power of a strong reducing agent.
Do you mean you were using supercritical fluid Cs? At 1665 deg C and 93 atm? I don’t think so. But it was inadvisable to heat it under any pressure with an oxide-based window. A diamond window might survive molten Cs at say, supercritical CO2 temperatures.
I did not realize Francium has that short of a halflife. Explains a lot.
What happens if you break a capsule of water in to Cesium?
And i want to see what happens if the water and sodium are both liquid.
First liquid sodium into water then water into sodium.
It will create a hole in the fabric of time and space
It would be interesting to see some cesium dropped into a vial of water with tall sides so it would contain the cesium, allowing it to react repeatedly as it falls back into the water.
If you melted the sodium/potassium before letting it out underwater would it be able to react in a similar instantaneous manner to cesium? My logic goes that pressure from the hydrogen gas would quickly rip the blob of sodium into tiny droplets with much higher surface area and thus force them to react quicker, as opposed to with a solid hunk, which only can react a little bit at a time at the very outside and has time to float to the top before doing anything drastic.
also heating the water would help as heat is a catalyst for most chemical reactions
Or making liquid alloy - NaK! I always wanted to pour it into the water :-)
Or mixing NaK and Cesium into a water bucket to open the gates of hell on your backyard.
What i learned from this is, no matter how much fire, or what ever problem you have. Enough water can deal with it!
Who needs caesium when my sodium exploded when it was submerged in water.
For those who want the full story:
When I was halfway through secondary school we did a demo of the alkali metals. At first it was going well, the Lithium was uneventful. Then we put the sodium in, initially for 2 seconds it reacted nominally with the water then it stopped, it just stopped. It stopped reacting almost completely for just long enough for our brains to process what was going on.
Then Boom, it just exploded, leaving smoke trails as tiny fragments were sent spiralling into the air. Thankfully we had an acrylic screen to protect us and we were all using safety glasses.
I must agree with the presenter, sodium is good fun.
Cesium you say? I suspect my back is made of this.
i dont remember wich one but thunderfoot did a video a while ago talking about why cesuim reaction in the bathtub was fake. if i recall the other metal was sapose to do more for some reson. maby idk
Cesium is heavier than sodium and sinks to the bottom, the few examples where cesium is thrown into a glass pneumatic trough (big glass bowl), the bowl always shatters.
Great job! Can you also do opening potassium metal vial underwater? Thanks.
I also want to see how does potassium metal reacts with water in vacuum or inert atmosphere or air/oxygen free atmosphere.
Can you do opening a hydrogen bomb underwater?
The slow mo guys should partner with you for something like this
I’m really enjoying your videos. I’m not a scientist. When you’re telling about these metals, sodium, cesium, etc, can you please say how they are mined? Not sure mined is a correct word, but how do these get collected and what industrial applications do they have?
Through electrolysis, you can easily look up the Wikipedia pages of these elements which will list both lab and industrial processes of producing these highly reactive elements
For anyone wondering, the list ends with Francium. Francium is more reactive than Cesium, which is more reactive than Rubidium, which is more reactive than Potassium, which is more reactive than Sodium, which is more reactive than Lithium. Francium would kick Lithium in its shit.
Someone, get this man a new cesium sample; he deserves it.
"frankeeum"💀
Cesium melts at 28.5 Celsius, which means it is solid at room temperature. It will melt with the warmth of one's hand as he demonstrated. There are only two elements that are liquid at room temperature (Hg and Br)
Maybe his room is 30 degree. But google says "Different institutes define different standard room temperatures but the worldwide accepted range of room temperature is taken from 20∘C to 25∘C". So ye...
@@d4slaimless thank you. Second comment I saw claiming room temperature to be above 25. That is a pretty warm room by my standards. I dunno the conversion but 68F is ”room temperature” to me, and that is definitely not 29C.
@@XiaolinDraconis there is quite a number of different standard conditions in different areas of science|industry. IUPAC suggests it is temperature of 273.15 K (0°C, 32°F) and an absolute pressure of 100 kPa. Accroding to NIST it is temperature of 20°C (293.15 K, 68°F) and an absolute pressure of 1 atm (101.325 kPa)
However there is also a term in thermodynamics "standard state". Standard state does not specify any temperature, but it is usually refer to 298.15 K (25 °C; 77 °F).
I think 25°C (77°F) is the most applicable number since phase transition is a thermodynamic process. Of course one might argue some different reasons.
Anyway be it 0°C, or 20°C or even 25°C Cesium is solid at those temperatures.
I loved science at school. I stole a lump of potassium or some other reactive soft metal metal that was in a jar of oil. I threw it down a drain at lunch time geese it exploded like I didn't expect it was about the size of my fist
For those of us who aren't too well versed in such stuff: How is your Caesium capsule, which you handle with your bare hands, different from the Caesium (137) capsule that threw Australia in a panic?
Cesium-137 is an isotope, whereas the cesium he is handling is the normal element.
An isotope is an alteration of an element with the same atomic number (which is the number of protons in the nucleus) but a different atomic mass (caused by a different number of neutrons).
Cesium-137 is an isotope with an atomic mass of 137 compared to the normal 135 of non-altered cesium.
Because of this difference, some isotopes are radioactive (wildly so in the case of cesium-137).
@@MatteoCampinoti94 the only thing I would add to help connect dots for the OP is that the smaller number of neutrons in the highly-radioactive cesium 135 means there's an imbalance between the forces keeping the nucleus together and the interior repulsive forces of the protons pushing against each other. That's what makes it unstable and so happy to split apart in radioactive decay.
is it radioactive ? Why could you hold that by bare hand ?
Thankfully no as the cesium he had in this video is basically pure cesium-133 which is stable i.e. non-radioactive rather than the radioactive cesium-137 (cesium with 4 too many neutrons) that you're thinking of which is a byproduct of nuclear fission of uranium.
cesium is actually a solid under ambient conditions, so unless you heated it with your hands to melt it (ca 28 °C), your sample very likely contained some other (earth) alkali metals as impurities stemming from the synthesis of the cesium
Most of the explosion is a coulomb reaction. The electrons between the metal and the water violently repel each other even before any hydrogen gas has been created. (Nature Chemistry "Coulomb explosion during the early stages of the reaction of alkali metals with water" Published 26 Jan 2015. Check out the article. It's really interesting and the high speed video is amazing.
Technically speaking the lighter the atom the more energy is released in that reaction, with lithium being the highest and cesium (discounting francium which you will never be able to test) being the lowest. However, more energy released does not equate to a more violent explosion since, as explained in the video, the reaction happens slowly and steadily instead of having everything going out at once.
Yup. He said all that....
Cesium 137 is my favorite radioactive isotope
I have always wondered how powdered Sodium would react. The surface area of a powdered sample should be much greater and increase the reactivity.
It would probably simply burn in air. Too much surface area and humidity in the air.
Isn't Cesium's melting point about 28 celsius? I thought mercury was the only liquid metal at room temperature (22 celsius). Please clarify because we have been teaching our students accordingly.
I think he kinda explains it already. Although implicitly.
It's in a vacuum capsule. The lower the air pressure is, the lower the melting temp is.
You can boil water by putting it inside a vacuum chamber without raising the temperature
@@koolkei I've seen vacuum capsule with Cesium and I can tell you it is certainly solid at room temperature (at least at 25ºC).
Influence of the pressure on the melting point is much much smaller than on boiling point. For water for example you need about 100 atm pressure to change melting point to 1 degree. Check the phase diagram for water, there is almost a straight line between solid and liquid state (means almost no change in meting point from changing pressure). No idea how it goes for Cesium, but I doubt there is big difference.
By what the accepted standard is for room temperature, it’s a solid. A very warm room or palm of your hand, it’s liquid.
Action lab is always the first 🥇
I wonder if the reaction would be especially violent if you spray the reactants at each other through fuel injectors, since they would be finely atomized in the air.
The thumbnail literally made me shiver, everyone who studied high school chemistry knows how dangerous it is

My biggest issue with cesium is how these reality science TV shows pretend to show off a cesium explosion but instead us a plastic explosive instead. Why pretend to be be educational when you are showing off fake demonstrations and are passing it off as real.
Can you please try this with NaK (Soduim + Potassium). It is also a liquid at room temperature. And highly reactive
Thunderf00t has a series on that. He was trying to figure out why it exploded, and he decided it's not hydrogen gas, but a columbic expansion. I'm hoping he turns it into a weapon.
amazing video!! Although for the future clipping nails is a must
Can you do a video explaining the suction effect I feel when being passed by a faster moving vehicle?
The answer lies in Mr. Bernoulli's explanation of pressures in moving systems. The total pressure is the sum of a static pressure and a dynamic pressure. You can experience this very easily when you hold two sheets of paper at finger's distance and blow air from your lungs between them. You might expect the papers to move away from each other because you add air and pressure in the room between them. The opposite is true. You replace a part of the static pressure between them with dynamic pressure that has a specific direction, so the static pressure on the outside is greater and pushes the papers together. It's the working principle of injector pumps, carburetors and aircraft wings.
I clicked on the video thinking it was backyard scientist 😅
Cesium is not a liquid at rt, it melts at like 84F, solidly above room temp, similar to gallium. Secondly, francium is not pounced like frank, its fran-see-uhm.
Ive been in many rooms that were 84f. Including joes room...
@potatopobobot4231 of course, a room in the Mohave desert could be way hotter than a room in iceland.. but "room temperature" is generally accepted to be 70F, or 20C. The difference in room temperature is exactly the reason that "room temp" is a specific number. And the only elements that are liquids at RT are mercury and bromine.
You should dilute the cesium in Mercury and aluminum.
He got that fire hair style !!
"Cesium is more expensive than gold" ... and you just literally/financially blew up some gold !
Crazy.
Love to know more things
NaK is the real deal. The combined energy and reactivity of potassium and sodium increased by the fact their alloy is liquid. Action lab should do that one under water. I'd think the explosion would be guaranteed there.
actually francium is less reactive than cesium and it is due to relativistic effects. but still Fr would be extremely reactive like Rubidium
So how would 1 gram of Cesium react to a few gallons of water completely sealed?
I can answer this
1 gram of cesium is 0.0075239 moles of cesium. moles of cesium and water react in a 1:1 ratio according to the equation
Cs (s) + H2O (l) -> CsOH (aq) + H2 (g)
While I don't speak gallons, I can take a wild guess that there are more moles of water present, making cesium the limiting reagant. Hydrogen gas is also produced in a 1:1 ratio, so this would make 0.0075239 moles of hydrogen gas. At 22 celsius and 1 atmosphere of pressure, the hydrogen produced would be able to expand to 0.1822 liters. of course, it would not be at 22 celsius or 1 atmosphere. I'm pretty sure the evolved hydrogen would be warmer than 22 degrees, and it's sealed, so whatever is used to contain the gallon might rupture. if it doesn't rupture, the hydrogen gas would be extremely pressurized
You need the Slo Mo Guys to film this.
So free electrons in Cesium is a thing? Does that mean it could be an electrical conductor?
If Cesium is that expensive, imagine Francium...
And that's especially given that Francium is even harder to keep around.
When I first learned about cesium, I thought, what would happen if you hid cesium inside a bar of soap? Could that be a lethal "prank"?
