Atomic mass value sometimes change over time in publications as scientists revise the natural isotope abundance of elements. 4 rows · thus, the mass number can be defined as the sum of the total number of protons and neutrons. It is a decimal number. This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number. Atoms of different elements usually have different mass numbers , but they can be the same.. This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number.
