18O Information

Oxygen is a colourless, odourless gaseous element belonging to group 16 of the periodic table. It is the most abundant element present in the earth's crust. This element also makes up 20.8% of the Earth's atmosphere. For industrial purposes, it is separated from liquid air by fractional distillation. It is used in high temperature welding, and in breathing. This element commonly comes in the form of Oxygen, but is found as Ozone in the upper atmosphere. Oxygen was discovered by Priestley in 1774. Oxygen has 16 isotopes, 3 of them are stable and naturally occurring.

Oxygen is used in steel making, welding, and supporting life. Naturally occurring ozone (O3) in the upper atmosphere shields the earth from ultraviolet radiation.
