The atomic mass
protons and neutrons have the same Mass so it you have 1 proton and ONE neutron the mass must be 2.
Don't confuse this with the mass from the electrons which are about 1/200 (approx.) of the proton.
Protons carry the positive charge.
Neutron have no charge.
Electrons carry the negative.
This why as a general rule the atomic mass is about twice the atomic number.
Hope this helps.

Mass number.
Certainly not atomic number, as several answerers have suggested, for that's the number of protons only!
