    If angular momentum quantum number can take value of n also (in addition to other possible values) then total number of electrons in first orbit would have been

    A)  2                     

    B)  6

    C)  8                    

    D)  10

    Correct Answer: C

    Solution :

     \[l=0,\,1,2...n\] instead of \[0,1,2...(n-1)\] \[\begin{align}   & For\,n=1\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Orbitals\,\,\,\,electrons \\  & l=0,\,m=0\,\,\,\,\,\,\,\,\,\,\,\,\,one\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,2 \\  & l=1,\,m=-1,\,0\,\,\,\,\,\,1\,three\,\,\,\,\,\,\,\,\,\,\,\,\,6\,\,\,\,\, \\ \end{align}\] Total no. of electrons \[=2+6=8\]
