All the lanthanide elements form generally stable compounds in +3 oxidation state. Then, why do cerium and europium form most stable compounds in + 4 and + 2 oxidation states, respectively?

Cerium and europium, though part of the lanthanide series, exhibit distinctive behavior in their oxidation states. Cerium primarily forms stable compounds in the +4 oxidation state because of its electronic configuration. In the +4 state, cerium has a stable _______ __________ ______ __________ ______.
