Chemistry Challenge

Chemistry is the scientific study of the properties and behavior of matter.

Chemistry covers the elements that make up matter to the compounds made of atoms, molecules, and ions and their composition, structure, properties, behavior, and the changes they undergo during a reaction with other substances.

Chemistry explains aspects of plant growth, the formation of igneous rocks, how atmospheric ozone is formed, how environmental pollutants are degraded, the properties of the soil on the moon, how medications work, and how to collect DNA.
