The quantum number of four electrons are given below : 

I.  n = 4, l=2 , m= -2, ms\(-\frac{1}{2}\)
II.  n=3, l=2, ml = 1, m\(+\frac{1}{2}\)
III.  n=4 , l=1, ml = 0, m\(+\frac{1}{2}\)
IV.  n=3, l=1, ml=1, ms=\(-\frac{1}{2}\)


The correct order of their increasing energies is:
1. I < III < II < IV
2. IV < II < III < I
3. I < II < III < IV
4. IV < III < II < I

The electrons identified by quantum numbers n and l can be placed in order of increasing energy as:

a. n = 4, l = 1

b. n = 4, l = 0

c. n = 3, l = 2

d. n = 3, l = 1

1. (d) < (b) < (c) < (a) 2. (b) < (d) < (a) < (c)
3. (a) < (c) < (b) < (d) 4. (c) < (d) < (b) < (a)

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)
