CHEMICAL meaning: 1 : 9611; 2 : 2 : a substance (such as an element or compound) that is made by a chemical process
A chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other species. When atoms approach one another, their electrons interact and tend to distribute themselves in space so that the total energy is lower than it would be in any alternative arrangement.
Chemical industry, complex of processes, operations, and organizations engaged in the manufacture of chemicals and their derivatives. Raw materials include fossil fuels and inorganic chemicals. An average chemical product is passed from factory to factory several times before it emerges into the market.
