Covalent bonds involve sharing of valence electrons. Very ionic crystals usually involve cations which are alkalis or alkaline-earths first two columns of the periodic table and oxygen or halogens as anions. The building criteria for the crystal structure are two: This leads to contact, configurations where anions have the highest number of cation neighbors and viceversa.

Prepared by Steve Murov. chapter 18 - electrochemistry Electrochemistry - a branch of chemistry that deals with the exploitation of spontaneous oxidation-reduction reactions to obtain electrical energy and the use of electrical energy to drive nonspontaneous reactions important in industrial extraction of certain elements.
Stoichiometry is a way of describing the quantitative relationships among elements in compounds and among substances as they undergo chemical changes.
