Chemistry [from Greek chemeia] An ancient art or science relating to the extraction of medicinal juices from plants, or of metals from their earths, or the transmutation of physical elements, as of base metals into gold, the preparation of elixirs, and other things usually connected with alchemy, from which modern chemistry is a derivative along specialized line. In The Secret Doctrine chemistry is mentioned as being, together with biology, one of the magicians of the future, especially in its form of chemical physics, when it is no longer the mechanistic science into which it has degenerated. "In Esoteric Philosophy, every physical particle corresponds to and depends on its higher noumenon -- the Being to whose essence it belongs; and above as below, the Spiritual evolves from the Divine, the psycho-mental from the Spiritual -- tainted from its lower plane by the astral -- the whole animate and (seemingly) inanimate Nature evolving on parallel lines, and drawing its attributes from above as well as from below" (SD 1:218).
chemistry \chem"is*try\ (k&ebreve;m"&ibreve;s*tr&ybreve;; 277), n. [from chemist. see alchemy.] 1. that branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. these atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. chemistry deals with the changes in the composition and constitution of molecules. see atom, molecule. note: historically, chemistry is an outgrowth of alchemy (or alchemistry), with which it was anciently identified. 2. an application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo. 3. a treatise on chemistry. note: this word and its derivatives were formerly written with y, and sometimes with i, instead of e, in the first syllable, chymistry, chymist, chymical, etc., or chimistry, chimist, chimical, etc.; and the pronunciation was conformed to the orthography.

Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.
