... The number of neutrons in an atom is equal to the difference between the mass number and the atomic number, or (A 2 Z). For example, if the mass number of a particular boron atom is 12 and the atomic number is 5 (indicating 5 protons in the nucleus), then the number of neutrons is 12 2 5 5 7. Note t ...
