[edit]f orbitals
[edit]- 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
[edit]Stability of +2 oxidation state
[edit]For most lanthanides, the most stable oxidation state is +3. But for few lanthanide elements, the +2 oxidation state is more stable.
Actinides
[edit]- Actinide
- Actinides in the environment
- Uranium in the environment
