Isotopes of an element are its different forms in which it has different atomic masses. The number of protons are equal in all forms but the number of neutrons are different.
For example, hydrogen has isotopes
Protium - one proton, no neutron (Atomic mass = 1)
Deuterium - one proton, 1 neutron (Atomic mass = 2)
Tritium - one proton, 2 neutrons (Atomic mass = 3)

isotopes of an element have same no of protons and eletrons but different no of neutrons
sailesh:
mark as best
is it essential that isotopes have same number of electrons ?
Yes
u hadn't written that.
Number of protons is always equal to number of electron in an element. We do not define isotopes of ions. So I think it is not necessary to mention it explicitly.
