Scientific definitions for oxygen
In 1786, the French chemist Antoine Lavoisier coined a term for the element oxygen (oxygène in French). He used Greek words for the coinage: oxy- means sharp, and -gen means producing. Oxygen was called the sharp-producing element because it was thought to be essential for making acids. Lavoisier also coined the name of the element hydrogen, the water-producing element, in 1788. Soon after, in 1791, another French chemist, J. A. Chaptal, introduced the word nitrogen, the niter-producing element, referring to its discovery from an analysis of nitric acid.
