    The ratio of the radius of the orbit for the electron orbiting the hydrogen nucleus to that of an electron orbiting a deuterium nucleus is

    A)  1 : 1                                      

    B)  1 : 2

    C)  2 : 1                                      

    D)  1 : 3

    Correct Answer: A

    Solution :

                     For an atom with atomic number A, the radius R of orbit is given by                                                 \[R={{R}_{o}}{{A}^{1/3}}\] Since, deuterium is an isotope of hydrogen both having the same atomic number, hence                 \[\frac{{{R}_{H}}}{{{R}_{D}}}=\frac{1}{1}\]
