Lanthanide contraction refers to the gradual decrease in the ionic radii of the lanthanide elements as atomic number increases, due to the increasing effective nuclear charge that pulls electrons closer to the nucleus. Europium is an exception because it has a half-filled f-orbital configuration (4f^7), which provides extra stability and results in a larger ionic radius compared to its neighbors, particularly in the +2 oxidation state. This stability allows Europium to exhibit a distinct electronic structure that deviates from the expected trend of lanthanide contraction.
