hi Sir ! I have a question. how to calculate maxiumum beta energy (0,634 MeV) of Flourine-18? I've tried to calculate using binding nuclear energy method but the result is different.
Is presence of extra electron for Nitrogen atom a pre condition for C-14 decay to proceed or Nitrogen atom first changes to an ion & then to Nitrogen atom once it finds an electron.
When we write mass of an element.. do we multiply mass of electron with total mass or mass of proton? E.g If I want to calculate mass of C-14.. will I multiply mass of electron with 14 or mass of proton ??
The neutron involved in beta decay is stationary inside atomic nucleus, but the electron shoots out of the nucleus at great speed. How can a stationary neutron inpart such a fast motion to electron?
If the neutron is part of an atom's nucleus, and if the atom is chemically bonded to other atoms, the mass of that structure is much much larger than the mass of an electron. (The mass of a neutron is almost 2000 times the mass of an electron, thus even with a single neutron, the kick back is rather minor.
Hi! I have another question, when we calculate the energy released, we have the E = deltam * c^2 formula. It's the mass of the nucleus minus the mass of the atom. The formula as I remember it is E = [m_p + m_n - m_A]c^2 But in some solutions in my physics book, they include the electron mass too even though the formula doens't, why is that?
Do alpha beta & gamma decay occurs in same element or it require different elements for different decay.. I.e, uranium to thorium it undergoes alpha decay.. why not beta decay takes place.. similarly carbon to nitrogen beta decay occurs why not alpha decay takes place..
Actually Mr. Michel you are stashing away almost all tge essence of Nuclear physics with excessive amount of simplifications. 1) Beta particle is not coming out of the nucleus; hence it has a positive charge but instead it is the antimatter versiok of electron arrising from Paul Dirac's statistics. 2) Secondly you are not doing an accurate thing by rebuffing the mass of a positron from your calculations. 3) Moreover, Beta decay releases an electron neutrino particle which despite is miniscule you ought to to include it as well. This has to do with the law of conservation of angular and linear momentum.

there is energy release because there is mass loss. The mass loss is converted to energy. E = mc^2
I love you
Sir how we ignore mass of the beta particle if it is breakdown from a neutron
Thank you so much! You answered all the questions I had :) Have a great day!
why is there energy release ? is it because the potential energy of the nucleus becomes greater ?

How could you use this to find how many beta particles are released using half-life for example
thank you sir

solved my problem
Life saver
So the neutron has to release the electron frist to transform into a proton
It is considered to be a beta particle

but u didnt add the neutrino
The neutrino makes up part of the energy released. It is indeed part of the beta decay process.
Hi!

It's the mass of the nucleus minus the mass of the atom.

But in some solutions in my physics book, they include the electron mass too even though the formula doens't, why is that?
Meant to say: Mass of the independent number of particles in the nucleus minus the total atomic mass
Do alpha beta & gamma decay occurs in same element or it require different elements for different decay.. I.e, uranium to thorium it undergoes alpha decay.. why not beta decay takes place.. similarly carbon to nitrogen beta decay occurs why not alpha decay takes place..
Every element has its unique decay particle.
Oh man
