Joseph Priestley discovered elemental oxygen in 1774. The word oxygen has a Greek origin. The parts that make up the word, “oxy genes,” mean acid rain. The element oxygen, abbreviated as “O,” occurs in two forms: oxygen (O2) and ozone (O3). According to the Royal Society of Chemistry, oxygen occurs naturally within the atmosphere. Oxygen constitutes 49.2 percent of the mass of the Earth’s crust and is an important constituent of all biomass.
