What are 3 uses for selenium?
Uses of Selenium Selenium is used in the glass industry to decolorize glass and to make red-colored glasses and enamels. It is used as a catalyst in many chemical reactions. Selenium is used in solar cells and photocells – in fact the first solar cell was made using selenium. It is also used as a photographic toner.Why is selenium named after the moon?
It was Berzelius who discovered selenium in 1817, as an impurity in sulphuric acid. Tellurium had already been discovered, and named after the Greek word for earth, so he named selenium using the Greek word for moon, selene.Where is selenium most commonly found?
SE-LE-NI-UM While rare, selenium is normally found in minerals. Of the lesser members in the sulfur family, selenium is the most abundant in nature, often found in copper and lead mining. Tellurium and polonium are other members in the same family (and found in the same column of the periodic table).How does selenium exist in nature?
It rarely occurs in its elemental state or as pure ore compounds in the Earth's crust. Selenium is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores, most often during production.Is tellurium toxic?
Appearance and Characteristics Tellurium is very toxic and teratogenic (can cause harm to developing embryos). Exposure to as little as 0.01 mg/m2 or less in air leads to “tellurium breath”, which has a garlic-like odor.
