oksigjen
Oksigjen, also known as oxygen, is a chemical element with the symbol O and atomic number 8. It is a colorless, odorless, and tasteless diatomic gas that makes up about 21 percent of the Earth's atmosphere by volume. Oxygen is essential for the survival of most living organisms, as it is a key component in the process of cellular respiration, where organisms convert glucose and oxygen into carbon dioxide and water, releasing energy in the form of adenosine triphosphate (ATP).
Oksigjen is highly reactive and forms compounds with nearly all other elements, including water (H₂O), carbon
Natural sources of oxygen include the atmosphere, water, and organic matter. It is also produced artificially
In everyday life, oxygen is often used in household appliances like oxygen concentrators or portable oxygen
