chemistry -

Chemistry is a branch of physical science that studies the order, structure, properties, and changes of matter. Chemistry covers topics such as the properties of atoms, the way atoms form chemical bonds to produce chemical compounds, the interaction of substances through intermolecular forces that produce the common properties of matter, and the interaction between substances through chemical reactions to form substances different.

Chemistry is sometimes referred to as central science because it bridges the natural sciences, including physics, geology, and biology.

Experts differ on the etymology of the chemical word. The history of chemistry can be traced back to alchemy, which has been practiced for several millennia in different parts of the world.
