But before Bergman could get more samples to study he died. Then 12 years later Muller sent a sample to Martin H. Klaproth who in Berlin  isolated the tellurium from the sample. In 1793, Klaproth publicly confirmed the existence of  the new element and it was named from the Latin word ‘tellus’ meaning Earth. In 1832, 34 years after the discovery of Tellurium, Jons Jacob Berzelius decided that tellurium was a metal, but belonged in the same group as the nonmetals in a detailed study, the reasoning was due to the similarities of their compounds. ]]> 2017-10-29 04:28:52 UTC https://padlet.com/391146/qq0o2w2myzlj/wish/201456858 391146 https://padlet.com/391146/qq0o2w2myzlj/wish/201457020 Tellurium is used to improve the  machinability of copper and stainless steel. It is a semiconductor that shows a greater electrical conductivity in certain directions or when exposed to light. Also when added to lead it decreases the corrosive action of sulfuric acid on lead and also improves it's strength and hardness. Tellurium is a basic ingredient in blasting caps and also is added to cast iron as chill control.]]> 2017-10-29 04:33:03 UTC https://padlet.com/391146/qq0o2w2myzlj/wish/201457020 391146 https://padlet.com/391146/qq0o2w2myzlj/wish/201457558 Tellurium is used in every day life because it makes stainless steel and copper more workable. It helps from corrosion in battery by decreases the corrosive action of sulfuric acid in the battery. It is used as a coloring agent in ceramics witch can be some peoples  livelihood. Cadmium telluride (CdTe) a compound using Tellurium is used as a thin film in solar panels to convert sunlight into electricity. Solar engender is a leading and renewable way that people get there energy.]]> 2017-10-29 04:48:13 UTC https://padlet.com/391146/qq0o2w2myzlj/wish/201457558 391146 https://padlet.com/391146/qq0o2w2myzlj/wish/201457586 https://www.chemicool.com/elements/tellurium.html
