Important facts Tellurium was discovered by Franz Joseph Müller von Reichenstein in 1782. Tellurium is a conductor that has a lot of electrical conductivity when exposed to light. It’s used to make blasting caps, added to cast iron. Tellurium makes metals more workable. Adding tellurium to led improves the strength and hardness of the metal and decreases corrosion. Its discovered in a mine with other elements. Tellurium is a naturally occurring element found in the earth's crust but is extremely rare. Tellurium compounds are the most common chemical compounds of gold found in it’s used in solar nature. Its obtained by a product of copper panels and lead.

Tellurium comes from the Color is silvery- latin word Tellus which white means earth.

Chemical properties: combines with gold, Doesn’t Physical properties: react with water. Shiny, soft, silver, white, grey, hard, electrical, conductivity,
