Explanation:
Detailed explanation-1: -Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons.
Detailed explanation-2: -The mass of a proton or neutron is about 1, 836 times larger. This explains why the mass of an atom is primarily determined by the mass of the protons and neutrons in the nucleus. The electron has other intrinsic properties. One of these is called spin.
