Another element in air is nitrogen.
Wilhelm Scheele discovered oxygen in Sweden.	History Air was explored by scientists all over the world and was known to be made up of two components but not known which elements formed air. It is now known to be nitrogen and oxygen. Oxygen was discovered in 1774 by Joseph Priestly (in England) who is the scientist who is credited for its discovery but Wilhelm Scheele (in Sweden) discovered it independently.	Joseph Priestly discovered oxygen in England.
Facts Most common element by volume or mass on the earth. 12 trillion tons of oxygen are in the air 21 % of the atmoshpere is made up of oxygen 3/4 of the human body is made up of oxygen Oxygen can also occur as a molecule with 3 atoms (O3) this makes up the ozone.		Model   Drawn by Zoe
Definition and Origin ox·y·gen n. Symbol O A nonmetallic element constituting 21 percent of the atmosphere by volume that occurs as a diatomic gas, O2, and in many compounds such as water and iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion. Oxygen comes from the Greek language. The word oxus meaning acid and the word gennan meaning generate .
Glossary Atmosphere- at·mos·phere 1.The gaseous mass or envelope surrounding a celestial body, especially the one surrounding the earth, and retained by the celestial body's gravitational field. 2.The air or climate in a specific place. Molecule- mol·e·cule 1.The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces. 2. A small particle; a tiny bit. Oxidation- ox·i·da·tion 1.The combination of a substance with oxygen. 2.A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased. Atomic- a·tom·ic 1.Of or relating to an atom or atoms. 2.Very small; infinitesimal. Electronegativity- 1. The likelihood that an atom or molecule will attract electrons, the strength of the attraction. 2.The tendency of an atom or molecule to become negatively charged. Combustion- com·bus·tion 1.The process of burning. 2.A chemical change, especially oxidation, accompanied by the production of heat and light. Respiration- res·pi·ra·tion 1. a.The act or process of inhaling and exhaling; breathing. Also called ventilation. b.The act or process by which an organism without lungs, such as a fish or plant, exchanges gases with its environment. 2. a.The oxidative process occurring within living cells by which the chemical energy of organic molecules is released in a series of metabolic steps involving the consumption of oxygen and the liberation of carbon dioxide and water. b.Any of various analogous metabolic processes by which certain organisms, such as fungi and anaerobic bacteria, obtain energy from organic molecules. Acid- ac·id 1.Chemistry. a.Any of a class of substances whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts. b.A substance that yields hydrogen ions when dissolved in water. c.A substance that can act as a proton donor. d.A substance that can accept a pair of electrons to form a covalent bond.
