Ozone gas,  (Ozone) is a gas composed of three oxygen atoms, and carries the chemical formula (O3) ,, also write this formula as such: (OO2) ,, Fgaz ozone is not only a form of oxygen, or in other words, ozone is a reactive oxygen gas, it is known that the regular oxygen molecules having only two oxygen atoms .
Ozone in English is called by other names, including: (trioxygen) and (Catena - trioxygen). Discoverer of ozone gas is the world of the German chemistry: Christian Frederick Honpin, discovered the ozone Honpin in 1839.
Ozone is characterized by a pale blue or pale yellow, and has a strong, strong odor similar to the smell of chlorine, and is in the atmosphere of the planet, and taken into account in the atmosphere is very low relative to rates caused by other gases making up the atmosphere of the planet, such as nitrogen, oxygen and carbon dioxide and hydrogen, the concentration level of ozone gas in the atmosphere of the Earth: 0.6 parts per million.
Ozone gas and an air layer which is concentrated ozone gas concentration are: the stratosphere or in English (stratosphere), which are also called b (Almtkor class), and the stratosphere is the second layer the atmosphere of the earth, this is the layer above the first layer in contact with the ground, and called (the troposphere).
 The ozone gas is concentrated in the lower portion of the stratosphere, which is itself a blue-called (ozone) sublayer, and the English (ozone), or (layer Ozonsphere ). Turns into oxygen gas (O2) in the stratosphere ozone gas produced by the ultraviolet radiation from the sun, which is exposed to oxygen, and rotates because of the ozone, this is the path which comprises where ozone is concentrated in the stratosphere gas and is itself a layer subset of great importance for the planet, the screens of the ozone layer on the basis of surface protection Earth from a large part of the middle ray and ultraviolet short, as they prevent the arrival of these harmful rays to the surface of the earth in large amounts, due to the ozone layer will not exceed short UV and average reaching the Earth 1%, the proportion of 99% of these rays are long packet, it is known that the concentration of short ultraviolet (UV-C) and medium (UVB) has a big and serious damage; affect humans, animals and plants, and is one of the most important reasons that lead to skin cancer.
