Mass Number & Atomic Mass The number of protons (+) and electrons (-) in an atom are the same (as long as the atom is neutral). The number of protons and neutrons (0) is not always the same.

Isotopes Isotopes are atoms of the same element having different masses due to varying numbers of neutrons. IsotopeProtonsElectronsNeutronsNucleus Hydrogen–1 (protium) 110 Hydrogen-2 (deuterium) 111 Hydrogen-3 (tritium) 112
