Tabla periódica

Chemical series of the periodic table

¹Actinides and lanthanides are collectively known as "Rare Earth Metals." ²Alkali metals, alkaline Earth metals, transition metals, actinides, and lanthanides are all collectively known as "Metals." ³Halogens and noble gases are also non-metals.

State at standard temperature and pressure

• those with atomic number in red are gases at standard temperature and pressure (STP)

• those with atomic number in blue are liquids at STP

• those with atomic number in black are solid at STP

Natural occurrence

• those with solid borders have isotopes that are older than the Earth (Primordial elements)

• those with dashed borders naturally arise from decay of other chemical elements and have no isotopes older than the earth

• those with dotted borders are made artificially (Synthetic elements)

• those without borders have not been discovered yet
