If this is a neutral atom ,
the number of protons=number of electrons
IF it`s electricity IS +X
its number of electrons+x=number of protons
IF its electricity IS -X
number of electrons-x=number of protons

No formula as such, but the number of protons equals the atomic number (from the periodic table).
For an atom, the number of electrons equals the number of protons.
If you have a positive ion the subtract the charge from the atomic number to give number of electrons.
If you have a negative ion add the charge to the atomic number.
Hope this is what you want.

Not sure I understand the question. They are both subatomic particules. Meaning that they are smaller than individual atoms. So if you're asking for a molecular formula, you are off-track.

in chemical reactions, H+ is a proton
in nuclear or subatomic reactions it is usually written 'p' or 'p+' though
electrons are always 'e-'

We usually use p and e. Or p+ and e-.
