Chemistry

Chemistry (from Greek χημεία khemeia^[1] meaning "alchemy") is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms, such as molecules, crystals, and metals. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in everyday life. Chemistry also deals with understanding the properties and interactions of individual atoms with the purpose of integration of this knowledge with known facts about larger scale matter in order to obtain a valuable outcome or make an accurate prediction for a given scientific work in which chemical facts are used. According to modern chemistry, the physical properties of materials are generally determined by their structure at the atomic scale which is determined by the properties and energies of the interactions.
