Chemistry

⧬ Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions. Their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

⧬ In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology),the properties of the soil on the moon (astrophysics), how medications wok (pharmacology), and how to collect DNA evidence at a crime scene (forensics).

⧬ Chemistry addresses topics such as how atoms and moleculed interact via chemical bonds to form new chemical compounds.
