Earth's atmosphere has different layers. The lowest layer is called the troposphere. We live in the troposphere. This page explains all about atmospheric chemistry in the troposphere.
Most of the gas in our atmosphere is nitrogen. About 4/5 of the air is nitrogen. But what about the remaining 1/5? Almost everything is oxygen, what is in the air that we need to breathe. But there are also small amounts of other chemicals.
Have you heard of greenhouse gases? These are the types of gases that trap heat from the Sun in our atmosphere. The Earth would be very cold if we did not have greenhouse gases. Carbon dioxide and methane are two very important greenhouse gases.
