Do electrons define the element? [closed]
In a nuclear reaction, protons and neutrons are exchanged and the resulting elements have a number of different protons and neutrons that uniquely define the element that we are studying.
However, can ...

How electron, proton and neutron have mass numbers
As far as I know, the mass number of an atom means the amount of protons and neutrons it has. For example, the mass number of Sodium (Na) is 23 since it has 11 protons and 12 neutrons. Then how ...

If electron fails to get into the lowest energy orbit after neutron decay does it remain bonded to the proton?
I have read this on Wikipedia:
A very small minority of neutron decays (about four per million) are so-called "two-body (neutron) decays", in which a proton, electron and antineutrino are ...

Difference between $e^-$ capture and $ β^+ $ decay
A nucleus stability is judged by it's n/p ratio, which it prefers to be ~1. If n/p ratio is much less than 1, an atom tries to increase neutrons and decrease protons present in the nucleus. My physics ...

Does an accelerating neutron produce electromagnetic waves?
I believe both protons and electrons do produce e/m radiation if accelerated, but what about a neutron which is made up of, or at least decays to, an electron and a proton?
If accelerating a neutron ...

Why neutron degeneracy pressure is much stronger than electron degeneracy pressure?
I am asking about Pauli Exclusion Principle stating that no two fermions can have the same 4 quantum numbers which is why we have periodic table of elements, but straight to my question: despite Pauli ...

How, exactly, does an electron scatter off of a neutron?
I thought about this recently because of news articles discussing the measurements of the 'neutron skin' of large nuclei....
Is it due to the fact that both have a negative magnetic moment?
Or to ...

Does the electron capture process ever occur in hydrogen?
I know that electron capture occurs more readily in heavier, often unstable atoms, but does it ever happen at all in a lighter atom?
I suppose, in ordinary hydrogen, a free neutron would then be ...

What is the SI unit for the mass of subatomic particles?
Question:
What is the SI unit for the mass of subatomic particles?
Notes:
The weight of a proton is about $1.7 \cdot 10^{-24}\mathrm g$. This is the same as 0.0000000000000000000000017 grams. This is ...

Can an electron and a proton be artificially or naturally merged to form a neutron?
My sense is that even though neutrons decay into a proton and an electron they are made up of quarks, it is not just some "merged" particle where, for example, the electron is orbiting the ...

Do neutrons have any attractive forces with electrons as they have with a proton? [closed]
the strong nuclear force is an attractive force between protons and neutrons that keep the nucleus together and weak force is responsible for radioactive decay. also, neutrino is lepton and positron ...
