Question

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

Answer 1

For a given n, 

l = 0 to (n – 1) 

And for given l, 

m_I = -l……, 0…….. + l

Therefore, 

The possible values of l and m for n = 3 are :

Value of b 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
