Atmospheric chemistry is the study of the chemical composition of the Earth's atmosphere, the reactions that occur among atmospheric components, and the interactions between the atmosphere and other parts of the environment, such as the biosphere, hydrosphere, and geosphere. In the environmental context, atmospheric chemistry is crucial for understanding air pollution, climate change, ozone depletion, and the overall health of the atmosphere.

An atmospheric deposition is the delivery of pollutants from the atmosphere to either land or water. Sometimes called "air

Atmospheric research involves the scientific study of Earth's atmosphere, focusing on understanding its composition, dynamics, and the processes that affect weather, climate, and air quality. This research is crucial for predicting weather patterns, assessing climate change, and understanding the environmental impacts of human activities.

Deutsch: Atom / Español: Atomo / Português: Atomo / Français: Atome / Italiano: Atomo
An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is made up of neutral or ionized atoms. Atoms are very small; typical sizes are around 100 pm (a ten-billionth of a meter, in the short scale).

Atomic energy is energy released in nuclear reactions. When a neutron splits an atom's nucleus into smaller pieces it is called fission.

An Atomic weight is the average weight (or mass) of all the isotopes of an element, as determined from the proportions in which they are present in a given element, compared with the
