Chemistry (derived from alchemy) is the science of interactions between matter at or near the atomic scale. Such matter includes atoms and collections of atoms (such as molecules, crystals, and metals) that constitute materials encountered in everyday life. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions. According to modern chemistry, the physical properties of materials are generally determined by their structure at the atomic scale. Chemistry is, along with physics, one of the most fundamental natural sciences.
Introduction
Chemistry is often called the central science because it connects other sciences, such as physics, material science, nanotechnology, biology and geology. Chemistry encompasses many specific specialized sub-disciplines that often overlap with significant portions of other sciences. Sub-disciplines, however, are very specific to chemistry, for example, they allow the manufacturing and testing of stronger materials, the synthesis of pharmaceuticals to treat disease, and determination of the mechanisms behind life processes.
A fundamental component of chemistry is that matter is involved. Chemistry may involve the interaction of matter with matter, or, involve matter with non-material phenomena such as energy. Most central and traditional to chemistry is the interaction of one substance with another such as in a chemical reaction where one substance or substances is transformed into another. This may involve electromagnetic radiation (as in photochemistry) where a chemical reaction is driven by the stimulation of light energy. However the chemical reaction is only part of a larger field that also studies matter in other ways. Chemical spectroscopists for example study the interaction of light with matter often without any reaction occurring.
