Q. No.Consider the following combination of n, l, and m values.
(i) n=3; l=0; m=0
(ii) n=4; l=0; m=0
(iii) n=3; l=1; m=0
(iv) n=3; l=2; m=0
The correct order of energy of the corresponding orbitals for multielectron species:
1. (ii) > (i)> (iv)> (iii)
2. (iv) > (ii) > (iii) > (i)
3. (i) > (iii) > (iv) > (ii)
4. (iv) > (iii) > (i) > (ii)
(i) n=3; l=0; m=0
(ii) n=4; l=0; m=0
(iii) n=3; l=1; m=0
(iv) n=3; l=2; m=0
The correct order of energy of the corresponding orbitals for multielectron species:
1. (ii) > (i)> (iv)> (iii)
2. (iv) > (ii) > (iii) > (i)
3. (i) > (iii) > (iv) > (ii)
4. (iv) > (iii) > (i) > (ii)

The quantum number of four electrons are given below :
| I. | n = 4, l=2 , ml = -2, ms = \(-\frac{1}{2}\) |
| II. | n=3, l=2, ml = 1, ms = \(+\frac{1}{2}\) |
| III. | n=4 , l=1, ml = 0, ms = \(+\frac{1}{2}\) |
| IV. | n=3, l=1, ml=1, ms=\(-\frac{1}{2}\) |
The correct order of their increasing energies will be:
1. I < III < II < IV
2. IV < II < III < I
3. I < II < III < IV
4. IV < III < II < I
