Selenium is a nonmetallic element with an atomic number of 34 and an atomic weight of 78.96. Its chemical symbol is Se. Selenium is most commonly found in nature in its inorganic form, sodium selenite. An organic form of selenium, selenomethionine, is found in foods
It is usually found in rocks and soil and sometimes fossil fuels. Selenium can also be released when volcanoes erupt. These are the natural sources; most sources of selenium are human-made.
Selenium is found in sulfide ores such as pyrite, where it partially replaces the sulfur.
The oxydation states of selenium are: -2, +2, +6, +4.
This depends on the concentration of selenium (or other chemicals) in the human body.
