Oxygen is the most abundant element on the earth’s surface, it represents by weight 46% of the Earth's crust, 89% of the Earth's water, 21% of the air we breathe, and 62% of the human body.

Oxygen  is a tasteless, odorless and colorless gas essential to life.

It can combine with all the other elements (except rare gases) in order to oxidize them and consequently produce energy.
