How many electrons could have the following set of quantum

numbers?

a.) n =2, ℓ =1

b.) n =3, ℓ =1, *mℓ* =-1

## Answer

a) n = 2, l = 1 means it should be P orbital.

So it will occupy total 6 electrons.

b) n =3, ℓ =1, mℓ =-1

based on these values, we can not set because

n = 3 means d orbital

l = 1 means p orbital.

l should be equal to 2
