Detailed explanation-1: -The correct option is the mass number. EXPLANATION: Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Detailed explanation-2: -all isotopes have the same number of protons and the same number of electrons. Because the electron structure is the same isotopes have the same chemical properties. What is different is the number of neutrons, The different number of neutrons all cause a difference in the atomic weight or mass of the atoms.
Detailed explanation-3: -Isotopes have the same number of protons but have different number of neutrons. Hence their atomic numbers are same but differ in mass numbers.
