NOTE 1 An atomic nucleus is composed of one or more protons and a number of neutrons (except hydrogen H), having thus a positive electric charge and nearly all the mass of the atom.

NOTE 2 The mass of the atomic nucleus is smaller than the sum of its constituents, due to energy binding them together.
