Priority is often given for Priestley because his work was published first. Priestley, however, called oxygen "dephlogisticated air", and did not recognize it as a chemical element. In 1777, Antoine Lavoisier first recognized oxygen as a chemical element and correctly characterized the role it plays in combustion. Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen along with its compounds accounts for nearly two-thirds of the mass of the human body and 49.2% of the mass of the Earth’s crust [1]. Oxygen gas is commercially extracted by fractional distillation of liquefied air [1]. Oxygen XML Editor is a cross platform tool setting the standard in XML editing.

Learn the normal ranges, chart, and symptoms of low oxygen levels (hypoxemia). Oxygen accounts for about 23% of the atmosphere's mass with pairs of oxygen atoms stuck together to make dioxygen molecules, but it's not just in the air, we breathe. The long-term sustainability of oxygen systems requires a holistic approach, and a resource ecosystem focused not only on oxygen production but also on distribution and delivery, ongoing maintenance and upkeep.
