If an atom has two electrons outside of its nucleus, what number of protons and neutrons must be contained in the nucleus to result in a neutral atom

Electrons have negative charge of -1
Two electrons would leave a -2 charge on the atom so there needs to be two protons which each have +1 charge. Neutrons are electrically neutral so it doesn’t matter all too much for how many neutrons there are.
