Mass number is the sum of neutrons and protons. It is equals to total of their weights. As an example hidrogen-2 (deuterium) has a mass number of 2.
Mass number is based on neutrons and protons. It is equals to total of their weigts. As a example Hidrogen has a mass number of 2.
Only the counting numbers can exist as atomic numbers. Fractions and decimals cannot be an atomic number.
