1. Mass number is the total number of neutrons and protons within the atom. 2. Atomic number is the amount of protons within the atom. 3. For neutral atoms, the electron number is the same as the atomic number. Example - Sodium (Na) Atomic number/number of protons = 11 Mass number = sum of protons and neutrons = 23 Number of neutrons = 23-11= 12 Number of protons = Number of electrons = 11 (since the sodium atom is neutral)
