प्रश्न

If n = 3, what are the quantum number l and m?

तक्ता

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
