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. For example, carbon has six protons and is atomic number 6.
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.
Detailed explanation-3: -Nuclei with the same number of protons but a different number of neutrons are called isobars.
Detailed explanation-4: -Atoms that have the same number of protons but different numbers of neutrons are called isotopes. The number of existing protons and electrons in a neutral atom of an element is equal.
