Feb 03, 2016 · The atomic mass is also different for every element, and also for isotopes of the same element. The atomic mass is equal to the number of protons that an element has plus the number of neutrons that an element has. This is because protons have a mass of approximately 1 amu (atomic mass unit) and neutrons have a mass of approximately 1 amu.
