Question

Which electron configuration of the 4f energy sublevel is the most stable?

A. 4f13

B. 4f14

C. 4f

D. 4f7

Answer 1

The most stable electron configuration for the 4f energy sublevel is 4f14 (B).

Step-by-step explanation:

The most stable electron configuration for the 4f energy sublevel would be 4f14 (B).

The f sublevels can accommodate a maximum of 14 electrons, so when all 14 orbitals are filled, it results in the most stable configuration.
