Chlorine/Discoverers
Carl Wilhem Scheele, a Swedish pharmacist, first described the greenish yellow gas in 1774 after dropping hydrochloric acid onto manganese dioxide. Sir Humphry Davy recognized the gas as an element in 1810 and named it based on the Greek word for its color, khloros. Chlorine was by this time already in use.
