Chemistry

Chemistry (derived from alchemy) is the science of matter at or near the atomic scale. Such matter includes atoms and the collections of atoms (such as molecules, crystals, and metals) that constitute materials encountered in everyday life. Chemistry deals with the composition and properties of such structures, as well as their transformations and interactions. According to modern chemistry, the physical properties of materials are generally predictable from their structure at the atomic scale. Chemistry is, along with physics, one of the most fundamental natural sciences.
