Description : 3f Why Orbital Impossible ?
Last Answer : 3f orbital impossible. This is because in the case of 3f orbital, the value of prime quantum number will be n = 3 n = 3 and the value of auxiliary quantum number will be l = 0, 1, 2 . But we know that s , p and d orbitals are possible for auxiliary quantum numbers 0, 1, 2 . So 3f is impossible.
