    The most probable radius (in pm) for finding the electron in \[H{{e}^{+}}\] is       [AIIMS 2005]

    A)                 0.0         

    B)                 52.9

    C)                 26.5       

    D)                 105.8

    Correct Answer: C

    Solution :

               Most probable radius = a0 / Z                    where a0 = 52.9 pm. For helium ion, Z = 2.                                 rmp = \[\frac{52.9}{2}\]= 26.45 pm.
