     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.
