The physical and chemical properties of oxygen are: Oxygen is available in all three forms, solid, gas and liquid. Required fields are marked *. These orbitals are classified as antibonding (weakening the bond order from three to two), so the diatomic oxygen bond is weaker than the diatomic nitrogen triple bond, in which all bonding molecular orbitals are filled, but some antibonding orbitals are not. Dioxygen is one of the common allotropes of oxygen. 3. Arriving from the Greek term chalkos, chalcogen signifies ore. Oxygen is a colourless, odourless, 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. All major classes of structural molecules in living organisms, such as proteins, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that comprise animal shells, teeth, and bone. Oxygen occurs in many compounds, including water, carbon dioxide, and iron ore e.t.c. By comparison, the density of air is about 1.29 grams per liter. Allotropes are forms of an element with different physical and chemical properties. Oxygen exhibits many unique physical and chemical properties.
