f orbitals

 * The Orbitron — 4f orbitals
 * Cubic set and general set exist — there is no unique set of real f orbitals, unlike the d orbitals
 * General set:
 * fx(x2−3y2)
 * fz(x2−y2)
 * fxz2
 * fz3
 * fyz2
 * fxyz
 * fy(3x2−y2)

Lanthanides

 * Lanthanide
 * Organolanthanide chemistry

Stability of +2 oxidation state
For most lanthanides, the most stable oxidation state is +3. But for few lanthanide elements, the +2 oxidation state is more stable.


 * Europium(II) sulfide

Actinides

 * Actinide
 * Actinides in the environment
 * Uranium in the environment
