Question

Why do the exceptional configurations taught in this class (only 1 electron moves from an s orbital to a d orbital) happen? (choose all that apply)
Because sublevel overlap results in the d sub level of one energy level being very close to the s sublevel of the next energy level

Because full sub levels are more stable than partially filled sub levels

Because half filled sub levels are more stable than partially filled sub levels

Because electrons want to be in the largest sublevel they can find.

Answer 1

Answer:

Because half filled sub levels are more stable than partially filled sub levels

Explanation:

The reason for the exceptional configuration found in some atomic orbitals is due to the special stability of half-filled sub-levels over partially filled ones.

One of the characteristic thing about filling some atomic orbitals we have to bear in mind that there is a stability conferred on an atom by being partially filled.

The energy needed to remove an electron from a half-filled configuration or inert gas configuration is very great.

This is why when there is a choice to have half-filled orbitals, it is desirous to go for this configuration.
