Question

Give the possible values of l,m,s for electrons having n=2 .​

Answer 1

Explanation:

For a corresponding value of principal quantum number(n), the azimuthal quantum number(l) ranges from 0 to (n−1). The values of magnetic quantum number(m) is governed by values of l it can have value between −l and +l through zero.

Therefore, for n=2 corresponding value of l ranges from l=0 and l=1 and magnetic quantum number ranges from m=−1 to m=+1.

Hence, an electron cannot have values n=2, l=2 and m=+2

Answer 2

There will be no possible values of l,m,n .

Only k shell=2
