    The angular momentum of an electron is zero. In which orbital may it be present?

    A)  2s                                          

    B)  2p

    C)  3d                                         

    D)  4f

    E)  5f

    Correct Answer: A

    Solution :

                    \[\because \]Angular momentum \[=\sqrt{l(l+1)}\frac{h}{2\pi }\] If angular momentum of an electron is zero then the value of \[l\] is also zero, therefore the electron may be present in s-orbital i.e. 2 s-orbital
