Chemistry is the clinical field worried with elements and compounds composed of atoms, molecules and ions: their composition, structure, homes, conduct and the adjustments they go through at some point of a reaction with other materials.
within the scope of its challenge, chemistry occupies an intermediate function among physics and biology. it's miles once in a while called the valuable science as it presents a foundation for knowledge each basic and carried out scientific disciplines at a essential level. as an example, chemistry explains elements of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is shaped and how environmental pollutants are degraded (ecology), the residences of the soil at the moon (astrophysics), how medicines work (pharmacology), and a way to accumulate DNA proof at against the law scene (forensics)
