The quantum number of four electrons are given below:
I.  n=4, l=2, ml=2, ms=1/2
II.  n=3, l=2, ml=1, ms=+1/2
III. n=4, l=1, ml=0, ms=+1/2
IV. n=3, l=1, ml=1, ms=1/2
The correct order of their increasing energies will be:

Options:

Answer:
B
Solution:

Higher the value ofn+lhigher will be energy.
Hence,3p4<3d5<4p5<4d7
Ifn+lsame, then higher the value of, higher will be energy.
