2.3.1 Isotopes

Isotopes

Isotopes are atoms of certain elements which have the same number of protons but different number of neutrons in the nucleus of the atoms.
It can also be defined as atoms of certain elements with the same proton numbers but with different nucleon numbers.
    Properties of Isotope
    Number of proton equal
    Number of neutron difference
    Chemical properties same
    Physical properties difference
