Oxigénmolekulákat

Oxigénmolekulákat refers to oxygen molecules. An oxygen molecule, with the chemical formula O2, consists of two oxygen atoms covalently bonded together. Oxygen is a highly reactive nonmetal and is essential for respiration in most living organisms. In its gaseous state at standard temperature and pressure, it is colorless and odorless. The Earth's atmosphere is composed of approximately 21% oxygen, making it the third most abundant gas. Oxygen plays a crucial role in combustion processes, as it is required for most forms of burning. In its diatomic form, O2, it is relatively stable but can readily form diatomic ions or react with other elements. The formation of ozone, O3, is another important allotrope of oxygen, which is vital for absorbing ultraviolet radiation in the Earth's stratosphere. Industrially, oxygen is produced through the fractional distillation of liquid air or by electrolysis of water. It has numerous applications, including in medical treatments, welding, and rocket propellants. The diatomic oxygen molecule is paramagnetic, meaning it is weakly attracted to a magnetic field.
