Oxygen, the “elixir of life,” was discovered by Joseph Priestly and Carl Wilhem Scheele independently of each other in the 1770’s. Oxygen is critical for life on Earth, produced by plants during photosynthesis and necessary for aerobic respiration in animals. Accounting for one fifth of the earth’s atmosphere, oxygen combines with most elements and is a component of thousands of organic compounds. Oxygen is colorless, odorless and tasteless in its gaseous form, and condenses to pale blue liquid and solid forms. Oxygen is a highly reactive element that promotes rapid combustion and is often used in industrial application.
