A brittle metal with a silver-white colour. Like water, bismuth is less dense as a solid than as a liquid (it expands as it cools), a property unique for a metal.


Elemental bismuth occurs naturally and its sulphide and oxide forms are important commercial ores.


Known since ancient times where it was confused with lead or tin due to similar resemblance.
