The subject chemistry started when during 600-1600 AD, chemical history was dominated by a pseudo-science called alchemy.

In chemistry, a composite refers to a material made up of two or more distinct substances with different chemical compositions. These substances are physically combined but do not undergo a chemical reaction to form a new compound. Composites often exhibit unique properties and characteristics that are different from the individual components.
The atomic theory is the basis of chemistry. This theory states that matter is composed of tiny, indivisible particles called atoms, which combine in specific ratios to form different compounds. Understanding the behavior of these atoms and their interactions forms the foundation of chemistry.
