    The angular momentum (L) of an electron moving in a stable orbit around mucleus is

    A)  half integral multiple of\[\frac{h}{2\pi }\]

    B)  integral multiple of h

    C)  integral multiple of\[\frac{h}{2\pi }\]

    D)  half integral multiple of h

    Correct Answer: C

    Solution :

                     For an electron to remain orbiting around the nucleous, the angular momentum (L) should be an integral multiple of\[h/2\pi \]. ie,  \[mvr=\frac{nh}{2\pi }\]where n = principle quantum number of electron, and h = Plancks constant
