State at standard temperature and pressure
 * those with atomic number in blue are not known at STP
 * those with atomic number in red are gases at (STP)
 * those with atomic number in green are liquids at STP
 * those with atomic number in black are solid at STP

Natural occurrence /Templates
 * those with solid borders have isotopes that are older than the Earth
 * 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

Unknown properties
 * those with a cyan background have unknown chemical properties.
