Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides ) with most elements. By mass, oxygen is the third- most abundant element in the universe, after hydrogen and helium . At standard temperature and pressure , two atoms of the element bind to form dioxygen , a colorless and odorless diatomic gas with the formula O 2 . Diatomic oxygen g
Many major classes of organic molecules in living organisms, such as proteins , nucleic acids , carbohydrates , and fats , contain oxygen, as do the major inorganic compounds that are constituents of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as it is a part of water, the major constituent of lifeforms. Oxygen is used in cellular respiration and released by photosynthesis , which uses the energy of sunlight to produce oxygen from water. It is too chemically reactive to re
