What is the common name for the molecule O3?

Ozone is the common name for the molecule O3. This molecule consists of three oxygen atoms bonded together, which distinguishes it from other forms of oxygen, such as the diatomic molecule O2, which is the most prevalent form in the Earth's atmosphere. Ozone plays a crucial role in the atmosphere, particularly in the stratosphere, where it forms a protective layer that absorbs the majority of the sun's harmful ultraviolet radiation.

In contrast to ozone, terms like "dioxide," "oxide," and "oxilate" refer to different types of chemical compounds. Dioxide typically refers to a compound containing two oxygen atoms bonded to another element, such as carbon dioxide (CO2). Oxides are broader in scope and include any compound that contains at least one oxygen atom and one other element. Oxilate does not refer to a standard chemical compound recognized in common terminology, making ozone the clear and precise answer to the question. Understanding the unique structure and function of ozone highlights its significance in environmental science and public health.
