Nitrogen

In 1772, Scottish physician and chemist, Daniel Rutherford made the discovery of Nitrogen. The name nitrogen comes from Latin "nitrogenium", where "nitrum" (from Greek nitron) means "saltpetre", and "genes" means "forming". Nitrogen is an inert gas, which is odourless and tasteless. This gas makes up 78% of the Earth’s atmosphere, however, Nitrogen is also found in the Earth's crust (to a limited extent: in the form of nitrates, etc.), in organic form (in the living or dead plants and organisms), in mineral form (ammonia), thus contributing to soil fertility.
