Hey, Tyler I was watching this video and suddenly realized halfway through, that this will probably be my last video of yours. I'm done with chemistry and I am watching this video for my physics diploma tomorrow for atomic physics. I just wanna say that you are the best teacher I have found on this platform and you are such an inspiration for the youth of today like myself. You're always smiling in your videos while teaching which just goes on to determine how passionate you are about teaching people. And I just want to tell you to keep making these videos and teaching the young people instead of making them memorize it. Signing off for now.
That's an interesting question. But a proton doesn't have a neutron and positron inside, it's just that it can turn into a neutron and positron. You know how a caterpillar can turn into a butterfly? We don't say that the caterpillar has a butterfly inside, we say that it can turn into a butterfly. So it's the same thing with the proton turning into a neutron and positron. Does that make sense?
so all the same "gene building blocks" but assembled "differently". (sorry this is the literal dumbest way i can put the caterpillar/butterfly into context with the components of a particle)
if you want me to answer this, you have to ask nicely. "i need the answer" is very demanding, and it's not very nice. if you ask nicely, i will answer it.
the short answer: something i thought was too complex to put in this video. the longer answer: neutrinos are like electrons, but they don't have a charge. when beta decay happens, an anti neutrino also gets shot out of the nucleus. and when positron decay happens, a neutrino gets shot out of the nucleus. you can find more information about this on wikipedia, or maybe on other youtube videos.
Great video, I just wanted to thank you for explaining every little step along the way. Too often educators on RUclips reference topics and ideas from previous videos when it would take half a second to explain it (like isotope notation for all radioactive decay). It makes it so much easier to jump in and get the information you need if youre in a time crunch!
great question! the atom will at first retain more electrons than protons and become an ion. but it's also possible that later on another atom will steal that electron, making it not have a charge anymore.
no, they are something additional. so in positron decay for example, a proton turns into a neutron, making a positron AND a neutrino. in beta decay, a neutron turns into a proton making a beta particle AND an antineutrino. the symbol for a neutrino is a lower-case v. the symbol for an antineutrino is a lower-case v with a line over it.
Great question. The important thing here is the difference between mass number and atomic mass--they sound the same but they're very different. That number 12.01 on the periodic table, that's not mass number--that's atomic mass. Same with 39.95 for Argon. Here are two of my video videos that should clear this up: first, watch "What are Isotopes?" and then watch, "What is the Difference Between Mass Number and Atomic Mass?" Hope this helps!
good question. it can be called either positron decay or beta-plus decay. positron decay is usually the more scientifically, technically-correct term, but you can call it either. because here's the thing--no one is saying that the positron is decaying. it's the *atom* that decays (and becomes another atom), not the positron. because with beta particles, you call it beta decay, but the beta particle isn't decaying either.
so here's what happens. all of these particles shoot out of the atom very fast, so they leave the nucleus, and they leave the atom and enter the outside environment. for example, if you have a piece of material that is doing beta decay, it is constantly shooting out beta particles, and you call that radiation or radioactivity. message me if you still have questions.
You are simply the best..awesome..the way you simplify things..wish college professors could grasp the concept of simplification..then perhaps we wouldn't have so many struggling students..in all subjects not only chemistry..
During electron-capture process on a radioisotope there is not necessarily an emission of a positron to take place. During this process, a proton within the nucleus capture nose-diving electrons to be embedded within its tip before transforming itself to a neutron. Generally, no positron emission will take place.Anderson detected positrons with a cloud chamber that enveloped with a fixed external magnetic field under the intense sunlight at high altitude. The energy of the sunlight is much weaker than the energy level within the nucleus. The eviction of a positron and an electron where those positrons are originated from the electron-shell rather than from within the electron-shell since the energy level of sunlight is weak that manage to evict some positrons from within an electron-shell. Therefore positrons must be from within the electron-shell; thus it should also be negatively charged particles. So, positrons having a similar charge like an electron except the positron has an opposite intrinsic direction than the one of an electrons; therefore positrons and electrons have opposite magnetic field than one another. Some argue that positrons are positively charged. If positrons are positively charged, then such positrons would evict from atom to atom as they would likely to be constantly repel by protons within the nucleus. But this is not true as confirmed by real observations. In conclusion, positrons must be negatively charged like those electrons except their intrinsic spin direction is opposite to the one of an electrons therefore they have opposite magnetic field from one another. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust..
Thanks sooo much for your videos.... Taking Chem on line and your videos are helping me understan the material... watched a few others but none as crystal clear as yours are. Thanks again...
I think your video could be better if you explicitly state that the Nucleus ejects the Beta decay +e and/or -e. But I'm a Civil Engineer changing careers to Nuclear Med Technology and am currently a student of NMT. Knowing what's happening in the nucleus helps me understand better
Oh my gosh thank you so much, we've been set homework for the start of sixth form and I couldn't find anywhere that was explaining it, but this was absolutely perfect and helped so much, thank you!
I am a physics student struggling to understand quantum physics. My question is how do the neutrinos play into this, considering that neutrinos have no charge and very tiny mass. What changed into the neutrino or where was the neutrino previously? Why is it that in a positron decay you have a neutrino produced while in a beta decay you have a antineutrino produced? What is the relationship between the two: antineutrino and neutrino?
1. Positrons and electrons are also waves. 2. When a positron and electron meet they annihilate into pure energy just like destructive interference of two mirror waves. 3. That suggests that positrons and electrons are mirror image waves.
Thank you-I can now understand what I read last week about solar fusion. I don't know how I was supposed to just say, "Okay, yeah, so now we've got protons turning into neutrons, that doesn't make me want to know why at all."
helps having a cute guy teach this. after watching the beta decay video I totally understood//// now I am reviewing positron decay. Your videos are extremely helpful. I am so glad your channel exists. You have saved me so much time b/c I don't have to read a textbook I just watch your videos and I get it :-)
@ttham11223344 the positron shoots away from the atom at a really high speed, like a bullet shooting out of a gun. so the positron shoots out of the atom and into the area that surrounds the atom. does that answer your question?
In chemistry we touched on radioactive decay but only for a small amount of time. It is Quantum or Nuclear Physics but all the science fields intersect at one point.
i got some questions. 1. Losing a proton would mean losing a electron, now would this lost electron react with the positron to destroy both of them? 2. What would happen to hydrogen in positron decay?
Thank you so much for your help. Without your videos, I am going to fail the chemistry regents. But I think i am going to pass with a 90+ after i watched all of your videos.
I'm quite new in chemistry stuffs, I don't understand why that Potassium (K) would want to change its proton into neutron when they, imo, already have a nice balanced neutron to proton ratio of 19 : 19? Is it because the periodic table revealed that K weight "should be" 39.098, which means the nice neutron to proton ratio is 20 : 19??? If that's the case, that might explain my prior question of why that Baron at 5:09 do not need to do Beta negative Decay with the "unbalanced" neutron to proton ratio of 6 : 5 it has. Aand again, if that is the case, my question would be, why is this uneven number of neutron and proton stable? This might be a very basic atom decay stuffs that I hadn't know 😶
*Hyun Jin Kim - 5 months ago* *I have a question..* *Th mass number of Carbon is 12 on the periodic table,, why did you use 11?* It's just a different isotope :)
Q: ) Why Is There Something Rather Than Nothing? A: ) Because Magnetism is an attractive force, not a repulsive force ? That's a guess, gravity is also an attractive force. Isaac Asimov in a book thought it was because there were more protons than electrons in the universe ( thus forming matter )
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
So in a way, the proton is losing its positive charge as a positron, and because it's positive charge is gone then it's a neutron with a neutral charge? Which contrasts to electron capture, in which an electron and a proton slam together and their charges balance out into a neutron with the energy being released as gamma?
Thank you for these!! Dusting off my chemistry books to take the DAT is a lot harder than I thought! One question though...in terms of Gamma decay, what would you consider to be the "problem" that initiates the chain of events to come? I couldn't find a video about Gamma decay but just getting that little piece of information would help me figure out the rest myself. THANKS AGAIN!
good video, I have one question. Why does it called "positron decay" ? Though positron has been formed when instead proton has been decayed. So why we can t call it a positron formation (or a proton decay)
great video thank you for sharing! I do have a question however; What are the main differences between positron decay and electron capture and what factors decide which phenomenon will occur?
I have a question, neutrons are heavier than protons (thus it would make sense for a neutron to decay to a proton), so how exactly do protons decay into neutrons?
I am confused. As a proton is made up of 2 up quarks and a down quark. A neutron made up of 2 down quarks and 1 up quark. How does a positron get made out of one quark switching from up to down?
1. I thought matter and antimatter annihilated each other. So how come the positron doesn't annihilate an electron from the atom? In which case it would really emit 2 gamma rays. 2. According to Wikipedia positron decay also creates an electron neutrino. 3. RUclips why can't I split up the text into separate blocks?
I tried to calculated positron energy by 18O(p,n)18F nuclear reaction, it should be 0.511 MeV. but I didn't get it. can you tell me more how to get 0.511 MeV?

Tyler DeWitt pleas sir explain pair production
Is this some kind of factor in time travel
Tyler needs to be cloned. I can see American academic scores rising every time he gives a lesson. Tyler rocks.

Almost 10 years later (25 Aug 2021), His video is helping someone, sitting a thousand miles away. Respect from Bangladesh :)

I was confuse when my Professor went over it but after watching this video I got that properly. Thanks Tyler it was so helpful.
Oh god can I just say that I don't usually watch a lot of physics videos on youtube but this was SO HELPFUL. You're an amazing teacher.
Still waiting for the video on positrons and anti matter :)

I'm learning this on the side while I have to deal with electrical engineering as my job; loving every second!
You are so f'n awesome. There should be more teachers like you with this clarity, passion and enthusiasm. Double thumbs up for you sir!!!
Wow, thank you!
Really love the way you take your time to teach.
Please someone get this guy to make more videos, he's great !!!!

My teacher puts me to sleep, luckily there's you!
Excellent format of video. Keep it up. The dual camera really helps ans so does your enthusiasm.
This man deserves way more than 1.29 Million subscribers
I don't know what would I do without you. Thank you
This was an excelent explanation, and Liked 👍 the colors, the didactic material you used for showing the new elements formed.
Love it I learn best Visually and You keep it simple, clear and concise

Eleanor Thurston I am 13 and studying it...
thank you!! you have been helping me in my subjects in chemistry for engineering
Awesome! Learned a lot from you!!! (No more sitting around science class not understanding anything from mono tone teacher)

I am so glad your channel exists. You have saved me so much time b/c I don't have to read a textbook I just watch your videos and I get it :-)
I love you Tyler. so much of a better teacher than my college profs. haha
pls add a video about gamma decay
You explain all this very well! Thank you very much!
@ttham11223344 the positron shoots away from the atom at a really high speed, like a bullet shooting out of a gun. so the positron shoots out of the atom and into the area that surrounds the atom. does that answer your question?
In UK this is Nuclear Physics how come it's Chem is US?
Jack Shaw Nuclear physics deals with the nucleus. Chemistry primarily deals with electrons, but can also deal with the nucleus.
It's Quantum Physics, is the term you were lookin for. :)
It can flow from the concept of atomic theory. In short (skipping lots): learn about the parts of an atomic and then ways an atom can break apart.
In chemistry we touched on radioactive decay but only for a small amount of time. It is Quantum or Nuclear Physics but all the science fields intersect at one point.
Lol, because when it comes to language, you Brits are crazy as hell. We say "toilet"; you say "loo". That says it all.
Honestly can't thank you enough! I LOVE YOU AND YOUR VIDEOS! You're amazing beyond words I love love love you and your videos!!
i got some questions.
1. Losing a proton would mean losing a electron, now would this lost electron react with the positron to destroy both of them?
2. What would happen to hydrogen in positron decay?
There is no Positron Decay on Hydrogen ( Protium) but There is is H3 ( Tritium)
best lecture I ever came across
Good video. Helped a lot when understanding nuclear decay.
Your videos are really great review for my chemistry test! I'm definitely coming back in the future! Thanks! :D
Thank you so much for your help. Without your videos, I am going to fail the chemistry regents. But I think i am going to pass with a 90+ after i watched all of your videos.
Thanks man, my science teacher told us that this type of decay exists, but she never helped us understand it!!!
You're amazing!!! Love all your videos. Thank you for helping me understand chemistry!!!
You explained this so well! Thank you :)
Impressive teacher....excellent communicator
Hello sir ur teaching
I had like very much
If it is possible please upload some videos on physics problems
I'm quite new in chemistry stuffs, I don't understand why that Potassium (K) would want to change its proton into neutron when they, imo, already have a nice balanced neutron to proton ratio of 19 : 19?

That's a guess, gravity is also an attractive force.
Isaac Asimov in a book thought it was because there were more protons than electrons in the universe ( thus forming matter )
Very concise and useful- greatly appreciated
Extremely clear and useful video! Could we state then that a proton is basically a neutron with a positive charged electron (positron) within it? :O

sorry not THEM CHEMISTRY

Very well explained. Smart young man. Thank you.
great video thank you for sharing!
I do have a question however;
What are the main differences between positron decay and electron capture and what factors decide which phenomenon will occur?
Is this beta plus decay?
+aura sayong yes it is
pretty much.
Yup
Good afternoon sir Tyler DeWitt sir, thank you sir for your teachings.
YOUR VIDEOS ARE AMAZING AND SO HELPFUL THANK YOU
you are the best teacher in the world
thank you from now to the end of the world
from iraq|ahmed ali
can positron decay occur in any elements. what i mean to say is ... how do i get to know which elements goes under positron decay?
omg your amazing !!!!!!!! my teacher took long to explain but i sill did not get it but now it seems so simplistic thanks !!!!
Why in the example potasium, the proton number and neutron number are same, but they still occur positron decay.
"just trust me" lol! I do trust you! Thank you for your amazing videos!
thank you for helping me so much with chem! keep up the great content! you're awesome!
Um, could you then in theory charge a neutron creating a proton? And why is the negative charge bound to never having mass?
What is the difference between beta ray and positron? Which one is captured by the nucleus?
where goes the antineutrino & neutrino in both negative beta decay and positive beta decay? Can you briefly explain? thank you.
please do a video on Gamma Emission
1:47 "but for right now, just trust me"
me: yes Tyler, yes whatever you say :')
thank you !!!
how does radioactive elements end up with unstable number of protons and neutrons
I have a question..
Th mass number of Carbon is 12 on the periodic table,, why did you use 11?
You explained this 10x better then my teacher
After 9 years i found all your videos on nuclear reactions very helpful . Thank you so much sir . Lots of Respect from pakistan 🌸.
I have a question, neutrons are heavier than protons (thus it would make sense for a neutron to decay to a proton), so how exactly do protons decay into neutrons?
So we can create materials out of other materials????
I am confused. As a proton is made up of 2 up quarks and a down quark. A neutron made up of 2 down quarks and 1 up quark. How does a positron get made out of one quark switching from up to down?
1. I thought matter and antimatter annihilated each other. So how come the positron doesn't annihilate an electron from the atom? In which case it would really emit 2 gamma rays. 2. According to Wikipedia positron decay also creates an electron neutrino. 3. RUclips why can't I split up the text into separate blocks?
positron and neutrino get emitted.
It can also be called Positron Emission
10:50 = my grade
"BIG CAPITAL F" this is so amazing
Very nice explaination
I love your analogy :) Thanks for the video
You just saved my chemistry final exam grade
I tried to calculated positron energy by 18O(p,n)18F nuclear reaction, it should be 0.511 MeV.
but I didn't get it. can you tell me more how to get 0.511 MeV?
So, would you say that Positron is the Reverse Flash to the Electron's Flash?
thank you so much for making this video,which helps me a lot!!
Does (Positron Decay) is a natural process or artificial, when does it take place
Sir where's the description of the neutrino and antineutrino.have u made any other video on it as well
You saved me in 9th grade and I came to repay you
you really are my favourite person. thank you so much! i understand it completely now! :)
