how will you calculate the mass number of argon,helium,phosphorus
Asked by viswa3659 | 13th Aug, 2020, 08:28: AM
The atomic mass number is calculated by the sum of all protons and neutrons in the nucleus. Mass number of argon =40, Helium= 4 u, phosphorus= 31 u.In case of different isotopes of the same element in nature, Atomic mass number is the average of the masses of isotopes.
