Answer 1

The correct answer is Ozone

Key Points

Ozone is a molecule composed of three oxygen atoms, making it a triatomic molecule.
In contrast, nitrogen (N₂), hydrogen (H₂), and oxygen (O₂) are diatomic molecules, consisting of two atoms each.
Ozone is represented by the chemical formula O₃.
It is a significant component of the Earth's stratosphere, where it forms the ozone layer, protecting life on Earth from harmful ultraviolet radiation.

Additional Information

Ozone can also be found at ground level as a pollutant, where it is a key component of smog and can have harmful effects on respiratory health.
The ozone layer in the stratosphere absorbs most of the Sun's ultraviolet radiation, preventing it from reaching the Earth's surface.
Ozone depletion due to human-made chemicals, such as chlorofluorocarbons (CFCs), has been a significant environmental concern, leading to international agreements like the Montreal Protocol to phase out the use of ozone-depleting substances.
