===Chemistry===

Constituting the scientific study of matter at the [[atom]]ic and [[molecule|molecular]] scale, chemistry deals primarily with collections of atoms, such as [[gas]]es, molecules, [[crystal]]s, and [[metal]]s. The composition, statistical properties, transformations and reactions of these materials are studied. Chemistry also involves understanding the properties and interactions of individual atoms for use in larger-scale applications. Most chemical processes can be studied directly in a laboratory, using a series of (often well-tested) techniques for manipulating materials, as well as an understanding of the underlying processes. Chemistry is often called "[[the central science]]" because of its role in connecting the other natural sciences.

Early experiments in chemistry had their roots in the system of [[Alchemy]], a set of beliefs combining mysticism with physical experiments. The science of chemistry began to develop with the work of [[Robert Boyle]], the discoverer of gas, and [[Antoine Lavoisier]], who developed the theory of the [[Conservation of mass]]. The [[Discoveries of the chemical elements|discovery of the chemical elements]] and the concept of [[Atomic Theory]] began to systematize this science, and researchers developed a fundamental understanding of [[Phase (matter)|states of matter]], [[ion]]s, [[chemical bond]]s and [[chemical reaction]]s. The success of this science led to a complementary [[chemical industry]] that now plays a significant role in the world economy.
