Ozone is composed of three oxygen atoms, which is denoted by its chemical formula O₃. This triatomic molecule forms when molecular oxygen (O₂) in the atmosphere is exposed to ultraviolet light or electrical discharges, leading to a reaction that causes the formation of the additional oxygen atom. The presence of three oxygen atoms gives ozone distinctive properties, such as its role in absorbing harmful ultraviolet radiation from the sun and its strong oxidizing ability, which is utilized in various applications, including disinfection and water purification.
