Answer:

The electronic configuration of La(Z=57) is [Xe]5d16s2. ... Therefore, addition of next electron doesn't occur in a more stable exactly half-filled 4f7 shell but occur in a little higher energy 5d-orbital+3

Adoption mainly of the +3 oxidation state. Usually found in crystalline compounds) They can also have an oxidation state of +2 or +4, though some lanthanides are most stable in the +3 oxidation state. Adoption of coordination numbers greater than 6 (usually 8-9) in compounds.
