Question
Which of the following sets of quantum numbers are correct?
| `n` | `l` | `m_l` | |
| (i) | 1 | 1 | +2 |
| (ii) | 2 | 1 | +1 |
| (iii) | 3 | 2 | –2 |
| (iv) | 3 | 4 | –2 |
Solution
| `n` | `l` | `m_l` | |
| (ii) | 2 | 1 | +1 |
| (iii) | 3 | 2 | –2 |
Explanation:
For the given value of n (principal quantum number) the value of 1 (Azimuthal quantum number) varies from 0 to n – l.
However for the given value of l the ml(magnetic quantum number) varies from –1 to +1
