    Maximum number of electrons in a sub shell with \[l=3\] and n = 4 is

    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 4f subshell \[=7\times 2\]           = 14
