Hello sir I have a couple of questions that are really bugging me :(( -How do protons turn into neutrons in positron emission when neutrons are heavier? -In my textbook, it says that the 'proton is the only stable baryon', meaning that it doesnt decay, but, in positron emission, they turn into neutrons?! -How do protons emit a W+ boson when the mass of a W+ boson is 80 times heavier than the mass of the proton itself? Thanks so much
If neutrons are more than protons, that nucleus will not do a positron emission, but will make alpha and beta emission. Same thing goes with if protons>neutrons, there's no spontaneous beta emission. And protons can decay into positrons and neutrons if nucleus is unstable. (p
if proton is an e+ and a neutron , in beta decay when neutron produces proton..how does that happen for proton you need neutron is neutron=e- + e+ + and a neutron? wtf I am really confused
No, it should be a positron. In beta decay (similar if you think about reverse of electron capture) a neutron is formed into a proton + e-; Neutron is formed by a proton + e- (electron) This separation is Beta Decay Proton is formed by a neutron + e+ (positron) This separation is Positron Decay electron + positron = 2 gamma particles which is completely different. If you do these in reverse that is called "atomic bombardment" which are all man made. Such as, you can bombard a nucleus with positrons that is "positron bombardment" and that will cause neutron + e+ = proton + gamma decay. Or: proton + e- = neutron + gamma decay. (This can be natural and called electron capture, shown in video) If it's human made, it is electron bombardment.
Nice narrating but charges of electrons and positrons should be written on top right, not bottom left. Just because of bottom left has the number of protons (atom number) and has an atomic mass which an electron/positron does have not.
BETA DECAY and My Model for PROTON and NEUTRON. Beta Decay takes two basic forms: BETA MINUS DECAY: a neutron breaks down into a proton and electron. Plus energy is released. BETA PLUS DECAY: a proton and electron combine to build a neutron. Plus energy is added. BACKGROUND of MY MODEL Proton = two positrons and one electron. Charge +1. Neutron - one proton and one electron. Charge 0. BETA MINUS DECAY: Neutron breaks down into a proton, and releases an electron.. Plus energy from an anti neutrino. BETA PLUS DECAY: Proton plus pair of virtual particles makes a neutron. Plus energy from a neutrino. OR Proton plus virtual electron makes a neutron and a virtual positron is released. Plus energy from a neutrino. THIS EXPLAINS Where the missing anti matter is - in protons and neutrons. Why a proton and electron have exact same opposite charge. Where the positron in beta plus decay comes from.
Electron capture is one mechanism of beta decay, along with the other beta decays. *Beta decay minus*: A neutron decays into a proton and electron. It also releases a gamma ray photon and an anti neutrino. *Beta decay plus*: A proton decays into a neutron and a positron (antimatter version of an electron). It also releases an gamma ray photon and a neutrino. *Electron Capture*: The electron from the lowest level orbital of the atom combines with a proton in the nucleus to make a neutron. It also releases a gamma ray photon and a neutrino. The gamma ray photon is released because the decay process releases energy, as the daughter nucleus is in a lower energy level. The neutrino/ anti neutrino release is a little more complicated, but we figured out it has to exist in order for the reaction to follow the law of conservation of energy and momentum.

reinforcing my concepts through your videos for my DAT exam. THANK YOU!!! amazing job
you are an amazing teacher! thank you for all that you do!
Thank! I appreciate that!
You're a great teacher!
Thanks Juan!
ur awesome man love ur work keep up the good work
very helpful for my chemistry class, my teacher actually recommended this video. Thank you!!!
thats awesome! you're welcome Mitch!
you are my hero! you explained this so well, I swear my college lecturer could take a leaf or two from your book!!!! lol :)
iluvjacobxxx thank you! :-D
man thank u
cleared up alot you are good teacher
Awesome!!! Thank you for your videos.
WOO,HVE NEVER SEEN SUCH KIND OF AN EINSTEIN .YU ARE THE BEST SIR
In gamma decay do u meant positron and electron for gamma ..right ??
you are a great teacher ..thanks alot for u
Thanx for the help
Definitely understand thank you

In beta decay (similar if you think about reverse of electron capture) a neutron is formed into a proton + e-;
Neutron is formed by a proton + e- (electron) This separation is Beta Decay
Proton is formed by a neutron + e+ (positron) This separation is Positron Decay
electron + positron = 2 gamma particles which is completely different.
If you do these in reverse that is called "atomic bombardment" which are all man made.
Such as, you can bombard a nucleus with positrons that is "positron bombardment" and that will cause neutron + e+ = proton + gamma decay.
Or:

Woow Your different 💘
Very informative! But what happens to all those particles released during each type of decay?
Thats called radiation
positrone makes annihilation and dissapears but in neutron e- and e+ are together and do not disappear ?
You're the best!
Thanks Daniel!
please how can proton decays to neutron his mass larger?
i love u sir,,,great

Neutron breaks down into a proton, and releases an electron..
Plus energy from an anti neutrino.

Proton plus virtual electron makes a neutron and a virtual positron is released. Plus energy from a neutrino.
THIS EXPLAINS
Where the missing anti matter is - in protons and neutrons.
Why a proton and electron have exact same opposite charge.
Where the positron in beta plus decay comes from.
Can someone explain the difference between beta decay and electron capture? Don't both use b^-1?
+RandomxRage Beta Decay is when the electron is released on the products side while electron capture is when it is on the reactants side.
Electron capture is one mechanism of beta decay, along with the other beta decays.
*Beta decay minus*: A neutron decays into a proton and electron. It also releases a gamma ray photon and an anti neutrino.
*Beta decay plus*: A proton decays into a neutron and a positron (antimatter version of an electron). It also releases an gamma ray photon and a neutrino.
*Electron Capture*: The electron from the lowest level orbital of the atom combines with a proton in the nucleus to make a neutron. It also releases a gamma ray photon and a neutrino.
The gamma ray photon is released because the decay process releases energy, as the daughter nucleus is in a lower energy level.
The neutrino/ anti neutrino release is a little more complicated, but we figured out it has to exist in order for the reaction to follow the law of conservation of energy and momentum.
There is no nutrino in beta decay
Can I ask for your email?

I have something between my legs that is going to make you really happy. Is my QUIZ I GOT 20/20! THANK YOU!
I see what you did there.
good good :)
