Question

What happens when d and f orbitals are completely filled?

Answer 1

Shielding is a phenomenon in chemistry in which the electrons in the inner orbitalprevents the electrons in the outer orbitalfrom the nuclear pull. So basically completely filled d and f orbital dont affect the size much due to poor shielding.

Answer 2

Explanation:

shielding is an phenomenonin chemistry in which the electron in the inner Orbit prevents the electrons in the outer Orbit form the nuclear pull.
