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

• nature. Its obtained by a product of copper

and lead. it’s used in solar panels

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

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