78Se Information

Selenium is a nonmetal element, belongs to group 16 of the periodic table. Multiple allotropic forms of selenium exist. This element resembles sulphur chemically. Selenium was discovered by Jons J. Berzelius in 1817. Selenium has 30 isotopes. 6 of them are naturally occurring, 5 of which are stable.

Light causes selenium to conduct electricity more easily. Selenium is used in photoelectric cells, TV cameras, xerography machines and as a semiconductor in solar batteries and rectifiers. Also this element colors glass red.
