Detailed explanation-1: -Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.

Detailed explanation-2: -the number of protons in all the atoms of a particular element is same, therefore to have different mass numbers, isotopes contain different number of neutrons. Q.

Detailed explanation-3: -Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

Detailed explanation-4: -Isotopes have same number of protons but different number of neutrons.

Detailed explanation-5: -The number of neutrons can be different, even in atoms of the same element. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.
