Which of the following sets of quantum numbers are correct?

         n        l        m1

(i)     1        1        +2

(ii)     2        1        +1

(iii)    3        2        -2

(iv)    3        4        -2

Answers (1)

The answer is the options (ii) and (iii)

As, in the case n = 1, then I ≠ 1, therefore option (i) is incorrect.

In case n = 3, I ≠ 4, therefore option (iv) is also incorrect.

In case, n = 2, I = 0, 1. When l = 1, then m =  -1, 0, +1. Therefore option (ii) is correct.

In case n = 3, l= 0, 1, 2. When l = 2, m = -2, -1, 0, +1, +2. Therefore, option (iii) is also correct.
