Document Summary
Best way to study: to go to through problem and how the theory or where i comes from. It is also helpful to be familiar with the nomenclature of compounds (section d) and oxidation numbers (section k) Metallic bond: large # of cations are held by sea of electrons. Ionic model: description of bonding in terms of ions. ,(cid:2869)(cid:2870) = (cid:4666)(cid:4666)(cid:2869)(cid:1857)(cid:4667) (cid:4666)(cid:2870)(cid:1857)(cid:4667)(cid:4667)/(cid:4666)4(cid:2868)(cid:2869)(cid:2870)(cid:4667)= (cid:4666)(cid:2869)(cid:2870)(cid:1857)(cid:2870)(cid:4667)/(cid:4666)4(cid:2868)(cid:2869)(cid:2870)(cid:4667) (cid:1852)(cid:2869) (cid:1853)(cid:1856) (cid:1852)(cid:2870) = charge numbers of two ions (cid:2869)(cid:2870) = distance between centers of ions (cid:2868)= vacumm permittivity.
