    Maximum number of electrons in a sub shell with \[l=3\] and \[n=4\] is                                  [AIPMT (S) 2012]

    A)  14         

    B)  16                   

    C)  10       

    D)  12

    Correct Answer: A

    Solution :

    n represents the main energy level and \[l\] represents the subshell.
     If \[n=4\] and \[l=3,\] the subshell is \[4f\].
    In \[f\] subshell, there are 7 orbitals and each orbital can accommodate a maximum of two electrons, so, maximum number of electrons in \[4\,f\] subshell \[=7\times 2=14\].
