I love the professor. He seems like he would make the best wise, old, kindly, grandfather that you could go up to and ask anything, and he'd be able to tell you.
I love that professor, he has such an interesting character. I love the chemistry focus, but if the videos were only about the professor's personal life it would be just as interesting.
I'm curious. If one had a powerful enough magnet could they start collecting oxygen out of the air? Seems like the more oxygen it gathered the more easily it would hold that oxygen as well. Or do you think a magnet that powerful would just grab everything out of the air?
@PeriodicElements What Mythbusters proved wrong is the myth that hydrogen had NOTHING TO DO with the explosion. But their second model (the one with the same coating as the Hindenburg) DID have small thermite reactions happening and accelerating the fire (although, NOT as explosive as their megadope model). At the end, they concluded that EVERYTHING was wrong with the Hindenburg: the lifting gas AND the coating. So: myth that the coating was the ONLY cause of the fire: BUSTED.
Francium has a half life of about 20 minutes and is one of the least abundant elements on Earth. Yes it'd be pretty dangerous, but the liklihood that you'll ever encounter more than a couple of atoms outside of a lab is so incredibly small that for all intents and purposes you could say it was harmless.
The element responsible for most deaths is probably Carbon, since diamonds are Carbon. However, Gold is a good idea too, espcially in more ancient times I think. No wait, my vote goes to Lead and Copper, since bullets are made of copper and/or Lead. Then again... Carbon is one of the ingredients of gun powder if I'm not mistaken.
@anothergazman So what are grounding rods be called in UK? I hope you know what I am talking about with the whole "...separated by a common language" problem.
Something he didn't mention about the Hindenburg's paint, is that it contained iron oxide and powdered aluminum. That mixture is thermite! It requires a very high temperature for ignition, but the spark from a static discharge is hot enough. The German authorities determined the cause of the accident. But they didn't publicly release their findings. They didn't want to let their future enemies know that their airships were painted with an incendiary mixture.
Some believe that the paint used to cover the Hindenburg was a mix that reacted together as thermite or was thermite. Mythbusters did this myth on one of their shows. My favorite element would have to be Cobalt.
The U.S. had a ban on helium exports, so it had nothing to do with Germany using the airships politically. The Hindenburg was designed to use Helium already in 1930-31, but the U.S. kept the ban so hydrogen had to be used instead. Helium was very expensive, and even in the U.S. they had to conserve the gas and not waste any.
Indeed. Mythbusters verified this a few years ago. If the paint was actual thermite, it would have burned completely differently than it did. As it is, the non-standard mockup with non-thermite-able paint and doping burned remarkably like the video.
i guess it depends on if you thinking of dangerous as the most violently reactive, or the most dangerous radioactively, or the most dangerous to human health. i believe he's taking the most violently reactive.
ha ha so many of those kids have braces on. I think I went to see him at Nottingham Uni when I was at school many many years ago, he did a lot of exploive stuff.
"I would say fluorine is the most dangerous element for sure. What DOESN'T it react with explosively?" ==There is no reply button for some reason. Plenty. For example, blow some F2 over graphite. It burns and produces CF4, but it doesn't explode. Explosion requires a mixture of gases and a source of ignition or some solid that turns suddenly into a gas. There are a couple of exceptions : copper acetylide and silver acetylide. These explode and produce 2 solids : the metal + graphite.
I'd have to agree with you there - when something is so reactive that it forms simple compounds (2 elements) with the Noble Gases, you have a really dangerous element on your hands. Fluorine,and Oxygen (I think possibly Nitrogen as well) are the only elements that this will work with...not even sure if I'm right. I could be wrong. Probably am too. Still - I agree Fluorine is the most dangerous.
I see you're already getting buffeted because of your choice of most dangerous. Obviously you were only thinking of the chemical properties. Check out some of the lethality stats on Plutonium. I seem to remember reading once that one GRAIN of Plutonium, atomized and distributed through the air of a large gymnasium, would have a near 100% lethality rate for anyone who walked through the room. I don't remember the source, so you can take it with a grain of SODIUM chloride. HAND
Well, yes, but francium is, well.. not so abundant, and pretty much impossible for humans to use. You could just as well call the next element in the alkaline metal group the most dangerous element, you know?
this is crazy invention, i see one fist inside of the aquarium, guy why dont put human in the water, so that can tell and feel the way burn with that chemical,for me these is a stupid inventiuon
I love the professor. He seems like he would make the best wise, old, kindly, grandfather that you could go up to and ask anything, and he'd be able to tell you.
I am thee most non scientific person you will ever meet but every time these vlogs come out I get so sucked into watching them...I love this channel.
Another wonderful video. I don't think people can really grasp how this series has helped me overcome my fear of science subjects.
I love that professor, he has such an interesting character. I love the chemistry focus, but if the videos were only about the professor's personal life it would be just as interesting.
The world adores you professor. ^_^

Do you think you can list the whole bottle collection?
I'm really surprised you had no Poland Springs...it's very common here in America.

great video! I'm proud to live in Nottingham! :)
These questions are from students in Rochester NY. The professor is simply answering some questions they had.
Thanks anothergazman. That is what I meant and a pretty good name for the device. Thanks for the additional information.
That is an awesome question. :D Can't wait to see if you get an answer!
The U.S. had a ban on helium exports, so it had nothing to do with Germany using the airships politically.

How cute. Water bottle donations, haha. I guess the Professor can expect many packages in the mail now won't he?

@periodicvideos YES, I'd say that gold is probably responsible for the most deaths out of any element....
Reminded me of the Led Zeppelin I album :D
wow, long time since ive seen steve, when i think over it
Most dangerous elements, in terms of total deaths caused, are gold and silver.
It is but its really rare, no ones ever made a large enough sample to do anything, plus its radioactive
2:46 lol
sodium is one of my favourite elemnts, becouse it's very common, usable and reacts violently with water, explosions,
yay!
How come he never answered the Mercury one? I was so curious!
Mythbuster's showed that it was the type of paint that was used (which was made of a type of thermite).
7:45 Water named "Poland spring"? Yay for Poland.
That was a huge chunk of sodium!!
What is Francium?
I was going to tell you how you were wrong, but you're not.
I have to agree with you on this one.
Yes it is.
what about lead :o
loved the vid
awesome!

Tell a New Yorker that New Jersey and New York are pretty much the same! HAHAHAHA
Okay I'm seriously freaked out right now. The guy at 0:02 looks and sounds like me.
obviously what kind of dog would hang around with all that banging going on :)

The 'experiments' with the alkali metals Li, Na, K, Rb Cs with water are most definitely don't try this at home.
'Still gives me a warm feeling...". Pundemonium.
Wouldn't Francium be the most dangerous element?
I'd have to agree with you there - when something is so reactive that it forms simple compounds (2 elements) with the Noble Gases, you have a really dangerous element on your hands.

Very Informative A+++++++++
The shelf collapsed? You should put some Hydrogen inside those bottles, to take some of the weight off the furniture. Wait, bad idea.
@ijunkie New Yorker here. I would definitely have been enraged if that came from an American lol
Al melts at about 660°C
I was referring to the fact that people kill each other over money.
And my favourite one : Uranium
The Professor is awesome. o.o-b

HAND
I;m starting a Arizona Ice Tea Collection
it was
who is to say that all life is not essentially evil. Think of all the greed and corruption in our societies
I thought that Francium was the last element in the alkaline metal group. O:
Well, yes, but francium is, well.. not so abundant, and pretty much impossible for humans to use.
You could just as well call the next element in the alkaline metal group the most dangerous element, you know?
Nice
Well, there's always a possibility for a bigger atom, only it might not be possible for us to produce, or present in our planet
Mythbusters tested Hindenburg.
Earthed? I guess that's British for grounded.
WTF?
Nottingham is in the UK? but all these kids are speaking with an American accent.
Carbon is the basis of all life...
My least favourite element : Astatine
this is crazy invention, i see one fist inside of the aquarium, guy why dont put human in the water, so that can tell and feel the way burn with that chemical,for me these is a stupid inventiuon
not really...
yes, lol
haha goodonya professor
why do you have your hairstyle like Einstein????????????
I find this Ironic Considering your name lol
Most dangerous something like flourine and potassium? What about stuff like darmstadtium? ;)
Haha true.
solomsolomol racist?
