Quizplus · Accepted Answer

Oxygen is a common gas in the atmosphere that is highly chemically active and combines readily with other elements. This is why it is essential for the process of respiration in living organisms and also plays a crucial role in many chemical reactions that occur in the atmosphere, such as the formation of ozone. Nitrogen, on the other hand, is relatively unreactive and is present in the atmosphere mainly as a diatomic gas (N2). Ozone is a highly reactive, although relatively rare, gas that is formed in the atmosphere when oxygen molecules (O2) are broken down by ultraviolet radiation.
