Document Summary
Sticking together of ions to form molecules (compounds: combining chemical elements to make mineral structures. Bond type and intensity critical: determines many properties of a substance i. e. hardness, cleavage, melting point . Four bond types important in minerals: in general, stronger bonds are harder, higher m. p, three of these bond types (ionic, covalent and metallic) involve valence electrons while the other two do not directly involve valence electrons. E) hydrogen bonding only end-members, transitions occur. Many minerals have more than one bond type (heterodesmic: if only one, called homodesmic. Both have outer shell noble gas configuration. September 29th, 2014 i. e. nacl, kcl, mgo image above: an idealized structure image with ionic bonding. Nacl (halite) structure shown here represents bonding between na+ and cl-. The distance between the centers of adjoining na+ and cl- ions is 2. 8 the attraction between oppositely charged ions constitutes the ionic (electrostatic) bond. Good conductors in solution, poor as solids.
