Scientific definitions for inorganic

[ ĭn′ôr-gănĭk ]

Not involving organisms or the products of their life processes.
Relating to chemical compounds that occur mainly outside of living or once living organisms, such as those in rocks, minerals, and ceramics. Most inorganic compounds lack carbon, such as salt (NaCl) and ammonia (NH3); a few, such as carbon dioxide (CO2), do contain it, but never attached to hydrogen atoms as in hydrocarbons. Inorganic molecules tend to have a relatively small number of atoms as compared with organic molecules.
