Which of the following is NOT a typical characteristic of ozone?

  1. Created after a lightning storm

  2. Contains two oxygen atoms

  3. Has antiseptic qualities

  4. Consists of three oxygen atoms

The correct answer is: Contains two oxygen atoms

The characteristic that is NOT typical of ozone is that it contains two oxygen atoms. Ozone is actually a triatomic molecule composed of three oxygen atoms, which is indicated by its chemical formula, O3. Ozone is formed naturally in the Earth's stratosphere and is most commonly recognized for its role in filtering harmful ultraviolet radiation from the sun. It can also be produced in the atmosphere through processes such as lightning storms when energy from the lightning causes oxygen molecules (O2) in the air to react and form ozone (O3). In addition to its formation process, ozone is also known for its antiseptic qualities, which make it useful in certain applications like sanitation and disinfection. These properties further demonstrate the importance of ozone in various environmental and health-related contexts. Recognizing ozone as O3 is crucial in understanding its functions and implications in both nature and technology.
