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: -Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
Detailed explanation-3: -A neutral atom has the same number of electrons as protons. Thus different isotopes of a given element all have the same number of electrons and share a similar electronic structure.
Detailed explanation-4: -The isotopes have same atomic number and different mass number. Thus they have same number of protons and electrons and different number of neutrons and nucleons.
