This is a standard display of the periodic table of elements. For more information on its contents and history, see the article Periodic table.
Notes
- Actinides and lanthanides are collectively known as "rare earth elements", a deprecated term. Regarding group membership of these elements, see here.
- 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 (0°C and 1 atm)
- those numbered in Template:Element color/Gas are gaseous
- those numbered in Template:Element color/Liquid are liquid
- those numbered in Template:Element color/Solid are solid
Natural occurrence
- those with dashed borders arise naturally from decay of other elements, and have no isotopes with a half-life comparable to the age of the Earth; however, some are found in trace amounts in radioactive ores
- those with dotted borders are synthetic elements, which do not occur naturally
- Note: Although californium (Cf, 98) does not occur naturally on Earth, Cf and its decay products occur in the Universe; their electromagnetic emissions are regularly observed in supernova spectra
- those without borders have not been discovered or synthesised yet
