<h3>What is oxygen ?</h3>
Oxygen is the name of the chemical element that has the atomic number 8 and the letter O. It is a very reactive nonmetal that is a member of the chalcogen group of the periodic table and an oxidizing agent that readily forms oxides with most elements as well as other compounds. The most prevalent element in the cosmos and on Earth, oxygen comes in third place after hydrogen and helium. At standard temperature and pressure, two of the element's atoms unite to form dioxygen, an odorless and colorless diatomic gas with the formula O2.
