- 1Natural lanthanides and scandium/yttrium are also known as "rare earths" or "rare-earth elements".
- 2Alkali metals, alkaline earth metals, transition metals, actinides, lanthanides, and poor metals are all collectively known as "Metals".
- 3Halogens and noble gases are also non-metals.
State at standard temperature and pressure
- atomic number in red: gas
- atomic number in blue: liquid
- atomic number in black: solid
Natural occurrence
- solid borders: at least one isotope is older than the Earth (Primordial elements)
- dashed borders: at least one isotope naturally arise from decay of other chemical elements and no isotopes are older than the earth
- dotted borders: only artificially made isotopes (synthetic elements)
- no borders: undiscovered
