WebbCORE – Aggregating the world’s open access research papers WebbEuropium does not demonstrate + 4 oxidation. The electronic configuration of Europium is [ Xe] 4 f 7 6 s 2. After losing 2 electrons, Eu achieves stability as the f-subshell will be half-filled but can lose 3 electrons also to achieve a +3-oxidation state also. For europium, the only oxidation states are +2 and +3.
