The mass number of an element is what

Splet17. nov. 2015 · The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons). In this case the mass number would be 11. Answer link SpletMass Numbers = (Number of Protons) + (Number of Neutrons) Mass Numbers - Atomic Weight I t is necessary to establish the atomic weight to enable you to establish the Mass Number.
