- Actinides and lanthanides are collectively known as "rare earth elements" (deprecated). IUPAC does not assign them a group number.
- Alkali metals, alkaline earth metals, transition metals, actinides, lanthanides, and poor metals are all collectively known as "metals".
- Halogens and noble gases are also non-metals.
State at standard temperature and pressure
- those with atomic number in #000000 are gases
- those with atomic number in #000000 are liquids
- those with atomic number in #000000 are solid
Natural occurrence
- those with dashed borders arise naturally from decay of other elements, and have no isotopes with half-life beyond or comparable to the age of the Earth (some can however be found in trace amounts in radioactive ores).
- those with dotted borders are synthetic elements.
- those without borders have not been discovered yet.
