Chemical Properties of Oxygen :
Oxygen is a highly reactive element, highly paramagnetic, and is easily capable of combining with other elements. One of oxygen’s most important chemical properties is that it supports combustion Oxygen also combines with elements at room temperature, for example, the formation of rust. Decaying is an example of oxygen reacting with compounds. Carbon dioxide and water are the main products of decay (Watch Chemical Properties of Oxygen Video to learn more).
Gaseous chemical element, symbol: O, atomic number: 8 and atomic weight 15,9994. It’s of great interest because it’s the essential element in the respiratory processes of most of the living cells and in combustion processes. It’s the most abundant element in The Earth’s crust. Nearly one fifth (in volume) of the air is oxygen. Non-combined gaseous oxygen normally exists in form of diatomic molecules, O2, but it also exists in triatomic form, O3, named ozone.
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
Oxygen is reactive and will form oxides with all other elements except helium, neon, argon and krypton. It is moderately soluble in water (30 cm3 per 1 liter of water dissolve) at 20 Celsius.
Oxygen in the environment:
The crust of earth is composed mainly of silicon-oxygen minerals, and many other elements are there as their oxides. Oxygen gas makes up a fifth of the atmosphere, amounting to more than a million billion tonnes.
Nearly every chemical, apart from the inert gasses, bind with oxygen to form compounds. Water, H2O, and silica, SiO2, main component of the sand, are among the more abundant binary oxygen compounds. Other compounds which are abundant in nature are calcium carbonate, calcium sulphate, aluminum oxide (bauxite) and various iron oxides, that are used as source of the metal.
