Question

What is the maximum number of electrons that can be associated with n=3,l=1and m=-1?

Answer 1

n = 3, Main shell = 3rd

l = 1, Subshell is p which has px, py, pz as suborbitals of which m=-1 can be any one

Using Pauli’s exclusion principle, each pi will have 2 electrons of spin +1/2 or – ½.

Hence for a given atom 2 electrons have this no. possible.

But, infinity is also possible, as for many atoms of diffnt. elements may have same quantum no.s
