    In the lowest energy level of hydrogen atom, the electron has the angular momentum

    A)  \[\text{ }\!\!\pi\!\!\text{ /h}\]                                

    B) \[\text{h/ }\!\!\pi\!\!\text{ }\]

    C)  \[\text{h/2 }\!\!\pi\!\!\text{ }\]                              

    D)  \[\text{2 }\!\!\pi\!\!\text{ /h}\]

    Correct Answer: C

    Solution :

    Angular momentum of the electron for nth level \[=\frac{nh}{2\pi }\] For lowest energy level of \[{{H}_{2}},\]\[n=1\] \[\therefore \]  angular momentum \[=\frac{h}{2\pi }\]
