Answer 2

Isotopes means nothing but they have same atomic number but different mass number that means they have same number of protons but they don't have same number of neutrons as that of protons.So because of existing extra neutrons only isotopes are existing.Isotopes means nothing but they have same atomic number but different mass number that means they have same number of protons but they don't have same number of neutrons as that of protons.So because of existing extra neutrons only isotopes are existing.
