Explanation:
Detailed explanation-1: -Adding one neutron to the nucleus of an atom increases its atomic number by one unit but does not change its atomic mass.
Detailed explanation-2: -Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.
Detailed explanation-3: -Fundamental Subatomic Particles The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
