Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Symbol: O
Atomic mass: 15.999 u
Atomic number: 8
Electronegativity: 3.44
Electrons per shell: 2, 6
Van der Waals radius: 152 pm
Discoverers: Joseph Priestley, Antoine Lavoisier, Carl Wilhelm Scheele
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.
