What is the chemical formula of ozone? \[ \begin{array}{l}\text { н2о } \\ \text { оз }\end{array} \]

Ozone is made up of three oxygen atoms, giving it the chemical formula O₃. This triatomic molecule forms a protective layer in the Earth's stratosphere, absorbing most of the sun's harmful ultraviolet radiation. So, while O₂ keeps us breathing, O₃ is our celestial sunblock! Interestingly, ozone is not only found high up in the atmosphere but also close to the ground, where it's a byproduct of pollution. It can lead to respiratory issues in humans and animals. So, while it’s vital up high, it's best to keep an eye on those smoggy, ozone-heavy city days down low!
