    In a radioactive change \[R\xrightarrow[{}]{-a}X\xrightarrow[{}]{-\beta }Y\xrightarrow[{}]{-\beta }Z\] R and Z are

    A)  isotope           

    B)  isobar

    C)  isomer          

    D)  isoneutronic

    Correct Answer: A

    Solution :

     In the radioactive charge \[_{A}{{R}^{B}}{{\xrightarrow[{}]{-\alpha }}_{A-2}}{{X}^{B-4}}{{\xrightarrow[{}]{-\beta }}_{A-1}}{{Y}^{B-4}}\] \[{{\xrightarrow[{}]{-\beta }}_{A}}{{Z}^{B-4}}\] Where, A = atomic number B = mass number R and Z are isotopes due to the same atomic number.
