Document Summary

Make an informed decision by picking your exam. 12. 7 till and including p. 461 (electronic materials, liquid crystals, ceramic materials) Metal atoms in a sample pool their valence electrons into a sea of electrons that flows between and around each metal core, thus attracting them together. Electrons in metallic bonding are not localized as in covalent bonding but are rather delocalized, moving freely throughout the metal sample. Instead of two li atoms interacting, consider 1 mole of. Instead of discrete lines get continuum (called a band) Mg atom n = 1 and n = 2 or [ne] 3s2. 1s2 2s2 2p6 3s2 core e (not interested) (filled called valence band) (empty called conductance band) (empty ignore as energy is too high) n = 3. In mg, the 3s band and the 3p are close to each other (in fact they overlap) e can travel through the empty conductance band conduct electricity and heat.
