    The\[\beta \]decay of a radioactive element results in the formation of its

    A)  isotope

    B)  isobar

    C)  isodiapher

    D)  nuclear isomer

    Correct Answer: B

    Solution :

     During \[\beta -\]decay, the mass number remains unaffected but atomic number increases by one unit and the species that have same mass number but different atomic number are called isobars. Thus, it is clear that \[\beta -\]decay results in the formation of an isobar.
