    What are the values of the orbital angular momentum of an electron in the orbitals Is, 3s, 3d and 2p?

    A) \[0,\,0,\,\frac{h}{2\pi }\sqrt{6},\frac{h}{2\pi }\sqrt{2}\]

    B) \[1,\,1,\,\frac{h}{2\pi }\sqrt{4},\frac{h}{2\pi }\sqrt{2}\]

    C) \[0,\,1,\,\frac{h}{2\pi }\sqrt{4},\frac{h}{2\pi }\sqrt{3}\]

    D) \[0,\,0,\,\frac{h}{2\pi }\sqrt{20},\frac{h}{2\pi }\sqrt{6}\]

    Correct Answer: A

    Solution :

    [a] From \[\sqrt{\ell (\ell +1)}\frac{h}{2\pi }\]             Values of 1 for 1s, 2s, 3d, and 2p are 0,0,2,1.             \[0,0,\frac{h}{2\pi }\sqrt{6},\frac{h}{2\pi }\sqrt{2}\]
