    The number of radial nodes of 3s and 2p orbitals are respectively.

    A) 2, 0

    B) 0, 2

    C) 1, 2

    D) 2, 1

    Correct Answer: A

    Solution :

    [a] Number of radial nodes = (n - l - 1)
                For 3s: n = 3, l = 0
                (Number of radial node = 2)
                For 2p: n =2, l = 1
                (Number of radial node = 0)
