    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 :

        Number of radial nodes \[=(n-l-1)\] For \[3s,\text{ }n=3,\text{ }l=0\] Number of radial node \[=3-0-1=2\] For  \[2p,\text{ }n=2,\text{ }l=1\] Number of radial node \[=2-1-1=0\]
