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

• those numbered in Template:Element color/Gas are gases
• those numbered in Template:Element color/Liquid are liquids
• those numbered in Template:Element color/Solid are solid

Natural occurrence

• those with solid borders are primordial elements, which have stable isotopes older than the Earth
• 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) doesn't 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
