Selenium

[Sarah]

A nonmetallic element of the sulphur group, and analogous tosulphur in its compounds. It is found in small quantities withsulphur and some sulphur ores, and obtained in the free state as adark reddish powder or crystalline mass, or as a dark metallic-looking substance. It exhibits under the action of light a remarkablevariation in electric conductivity, and is used in certain electricapparatus. Symbol Se. Atomic weight 78.9.

Element #34 with the symbol Se. Selenium usually comes as a smooth, black, glossy solid, like a chunk of [sexy chocolate]. It can also occur as a red powder, which is much more reactive than the black counterpart. Selenium has many applications in todays world, such as being a key ingredient in vitamin supplements and shampoos, solar cells, photoconductors, batteries, fertilizers, and glass production. One property unique to Selenium is that it is quite sensitive to light. This strange characteristic paved the way for the development of solar panels and other devices that utilise light/electricity. Selenium gets its name from the Greek [Selene], which means moon. The reason for this is because at the time of its discovery, Selenium was placed directly above [Tellurium] on the periodic table. And [Telluriums] name was derived from the Latin Tellus, which meant earth. It made perfect sense to name an element after a celestial body with correlation to another similarly-named element.
