    In a multi-electron atom, which of the following orbitals, described by the three quantum numbers, will have the same energy in the absence of magnetic field and electric field? (i) \[n=1,l=0,m=0\] (ii) \[n=2,l=0,m=0\] (iii) \[n=3,l=1,m=1\] (iv)  \[n=3,l=2,m=1\] (v) \[n=3,l=2,m=0\]

    A) (i) and (ii)              

    B) (ii) and (iii)         

    C) (iv) and (v)            

    D) (iii) and (iv)

    Correct Answer: C

    Solution :

    In a multi-electron atom, orbitals (IV) \[n=3,l=2,m=1\]and (V) \[n=3,l=2,m=0\]will have the same energy as energy corresponds to \[(n+l)\]value.
