@WhatTehHeck the number of protons won't change

Answer 8

remember protons are inside the nucleus while electrons are outside of it.



the number of electrons can change and that will result in an ion.

if there are more protons than electrons you'll get a positive ion cation.
that's if you've lost electron/s

if you've gained an electron, the result will be an anion.

but the number of protons = the identity of the element.
