Unformatted text preview: 1. Mini exam, next week in discussion sec When atoms form bonds as energy release because the resultant has a lower energy level; but at some circumstance energy might be absorbed. Classical Bonding- bonding explains chemical activities and reaction- explain biological processes, why one molecules will bond to one acceptor. e.g. designing molecules.- description: Class Bonding Modifs- Ionic: electrostatics (+ --> -)- Coulombs Law- Covalent: shared electrons- some eletrostatics involved in- metallic: "sea" of electrons around metal "cation"- imagine silver as positive and positioning among the electrons as they move around- Coordinate convalent: a shared arrangement not unlike pure covalent e.g. A+B --> AB even sodium chloride is only 80% ionic bond- electrons are involved in bonding- Valence e`s is important for bonding- Core e`s is not important for bonding Ionization E (IE) Electron Affinity (EA) Both have periodic table trend IE X(g) --> X+(g) + e`(g) change in E=IE1 What we studying = system what we don't study = surrounding when energy goes out from the system, the ^E is positive if E must be added, negative if E is given...
