The atomic mass of an atom is the number of protons and neutrons found in the nucleus of an atom. The atomic mass is usually a decimal number. When determining the number of neutrons, round the atomic mass to the nearest whole number. For example, the atomic mass of beryllium is 9.0112 so you would round that to 9.
