प्रश्न
If n = 3, what are the quantum number l and m?
Advertisements
उत्तर
For a given n, l = 0 to (n − 1) and forgiven l, ml = −l...., 0, ..... + l
Therefore, the possible values of l and ml for n = 3 are:
| Value of n | Value of l | Values of ml |
| 3 | 0 | ml = 0 |
| 1 | ml = −1 ml = 0 ml = +1 |
|
| 2 | ml = −2 ml = −1 ml = 0 ml = +1 ml = +2 |
