Question

An atomic orbital has n=3.What are the possible values of I and mı?​

Answer 1

Answer:

For a given value of n, l can have values from 0 to (n-1).

∴ For n = 3 , l = 0, 1, 2

For a given value of l, ml can have (2l+1) values.

When l = 0, m = 0

l = 1, m = – 1, 0, 1

l = 2, m = – 2, – 1, 0, 1, 2

l = 3, m = -3, -2, -1, 0, 1, 2, 3

(ii) For 3d orbital, n = 3, l = 2.

∴ For l = 2

m2 = -2, -1, 0, 1, 2

(iii) 1p is not possible because when n = 1, l = 0. (for p, l = 1)

2s is possible because when n=2, l = 0,1 (for s, l=0)

2p is possible because when n=2, l = 0,1 (for p, l=1)

3f is not possible because when n=3, l = 0, 1 , 2 (for f, l=3)

Answer 2

Answer:

2,8

Explanation:

as the first shell is filled we will go to second

as second shell is filled we will go to shell

so l=8

m=16

n=3
