Two atoms bonded together…

Oxygen is a gas that is made up of two atoms of oxygen bonded together. It is a colorless, odorless, and tasteless gas that makes up about 21% of the air we breathe.

Oxygen is necessary for human life and is used by our cells to produce energy. It is also used by plants to produce oxygen gas during photosynthesis.

Oxygen is an important gas in the world around us and plays a vital role in supporting life.Oxygen is produced naturally by the Earth’s atmosphere, but it can also be produced artificially using oxygen tanks or concentrators.

While oxygen is essential for life, too much oxygen can be dangerous. Oxygen toxicity can occur when a person is exposed to high concentrations of it, and can lead to cell damage and respiratory problems.
