Question

Which of the following orbitals are not possible and why
1p,3s,2d,4f,

Answer 1

Answer:

1p and 2d orbitals do not exist in nature or not possible.

Explanation:

1p orbital have principal quantum number, n is of 1,whereas azimuthal quantum number, l is of 1.

But n never =l, as l belogs to (n-1) .

in 2d orbital, n=2 and l=2

and even said earlier n never =l
