CHEM 1061 Chapter Notes - Chapter 8-11: Diamagnetism, Octet Rule, Ionic Compound
Document Summary
8-11 in chemistry; the molecular nature of matter and change. Includes: electron configuration, periodic table trends, types of bonds, lattice energy, lewis. Structures, vsepr, bond order, bond length, formal charge, and hybridization. Spin quantum number: (ms) corresponds to direction of electron"s field. For any n value, a lower l value indicates a lower (more stable) sublevel. Exclusion principle: no two electrons in the same atom can have the same four quantum. Shielding: reduces the full nuclear charge to an effective nuclear charge making it easier to remove an electron. 1s2 2s2 2p6 3s2 3p6 4s 2 3d10 4p6 etc Periodic table trends: atomic size (transition elements stay about the same size), ionization energy , electron affinity , metallic behavior (memorize periodic table trends chart). Paramagnetic vs diamagnetic: paramagnetic have an unpaired electron which is attracted to an external magnetic field. Diamagnetic have no unpaired electrons, not attracted (slightly repelled) by magnetic fields. Ionic bond: between a metal and a non-metal.
