An ozone molecule contains:

An ozone molecule is specifically comprised of three oxygen atoms bonded together, resulting in the formula O3. This structure is significant as it forms a distinct layer in the Earth's stratosphere, playing a critical role in absorbing the majority of the sun's harmful ultraviolet radiation. The presence of three oxygen atoms, compared to diatomic oxygen (O2), gives ozone its unique chemical properties and behavior in atmospheric chemistry. Understanding the molecular composition of ozone is essential, especially in discussions about environmental science and the impact of ozone depletion.
