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 dioxide (CO₂), and oxides. It is crucial in various industrial processes, such as the production of steel, glass, and chemicals. In medicine, oxygen therapy is used to treat conditions where oxygen levels in the blood are insufficient, such as respiratory disorders or severe infections.

Natural sources of oxygen include the atmosphere, water, and organic matter. It is also produced artificially through various methods, such as fractional distillation of liquid air or electrolysis of water. Oksigjen plays a vital role in combustion, where it reacts with other substances to produce heat and light, forming oxides as byproducts.

In everyday life, oxygen is often used in household appliances like oxygen concentrators or portable oxygen tanks for individuals with breathing difficulties. Its importance in sustaining life and driving numerous industrial processes underscores its fundamental role in both natural and human-made systems.
