In aqueous solutions Eu2+ acts as

Eu2+ is a strong reducing agent because Eu3+ is more stable than Eu2+. Yb in +2 oxidation states acquires half filled-4f7 and fully filled-4f14 configuration. Tb in +4 state has 4f7 half-filled stable configuration but it readily gets reduced to common oxidation +3 state.

Detailed Solution

Eu²⁺ is a strong reducing agent because Eu³⁺ is more stable than Eu²⁺. Yb in +2 oxidation states acquires half filled-4f⁷ and fully filled-4f¹⁴ configuration. Tb in +4 state has 4f⁷ half-filled stable configuration but it readily gets reduced to common oxidation +3 state.
