     Any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei. As a consequence, atoms for the same isotope will have the same atomic number but a different mass number (atomic weight).

    OR

    Isotopes:  Atoms of the same element with the same atomic number but different mass numbers are called isotopes.
    Examples: 1H1, 1H2, 1H3 are the isotopes of hydrogen,6 C12 ;6C13  are isotopes of carbon.
    The chemical properties of all the isotopes of an element are the same. This is due to the presence of same number of electrons.

    By lossing the valance shell. If its has less than 4 i.e 1,2,3 then their valancy is same and if its valancy is more than 4 then subtract it from 8 and you will get valancy

    By splitting the atomic no. into shells K L M N. For eg. the atomic no. of hydrogen is 1 first shell can contain 2 atoms but hydrogen has one atom so it must gain an electron therefore the valency of hydrogen is 1
