The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atoms electrons has been assigned a unique set of quantum numbers.

If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoesradioactive decay.

For hydrogen, 1.008 is closer to 1 than 2, so let's call it 1. As you might have already guessed from its name, the neutron is neutral.
