Chemistry
Chemistry
Chemistry (pronounced: /ˈkɛmɪstri/) is a branch of science that involves the study of the composition, structure, properties, and changes of matter. The term "chemistry" comes from the word chemia, a term used in the 16th century to refer to the art of transmuting metals.
History
The history of chemistry can be traced back to the alchemy of the medieval period. Alchemy was a philosophical and protoscientific tradition that aimed to transform base metals into noble metals. The modern discipline of chemistry began to develop in the 17th century with the work of Robert Boyle and other pioneers.

Chemistry is divided into several branches, including:
- Analytical chemistry: The study of the composition of matter.

- Inorganic chemistry: The study of inorganic compounds and minerals.
- Organic chemistry: The study of organic compounds, primarily those containing carbon atoms.
- Physical chemistry: The study of the physical and chemical properties of matter and the changes it undergoes during chemical reactions.
