Oxygen is a common gas available in the air it accounts to 208% of all gases in the air it is chemically represented as “o” and element oxygen is represented as o2 it is one of the widely distributed gases in the atmosphere after nitrogen it is a diatomic molecule with an atomic number of 8 and the molecular weight of 16. Oxygen is the most common chemical element found on or in earth it is one of the main elements that make up air, and it is necessary for the survival of all plants and animals scientists use symbols to stand for the chemical elements the symbol for oxygen is ooxygen makes up about one fifth of the atmosphere. Lavoisier considered as father of modern chemistry and was a french nobleman prominent in the histories of chemistry and biology in 1783, he was the first person to succeed in determining the composition of water and in synthesizing the compound from its elements lavoisier coined name as oxygen in the year of 1778. Oxygen is usually found in the air and water although it is mixed with many other elements the way to get oxygen by itself is through electrolysis of the water in which electricity is run through water until it separates into oxygen and hydrogen another way is to cool the air until separate elements turn into.
