Aspects of Chemical Bonds Bonding in Chem 1a

Aspects of Chemical Bonds Bonding in Chem 1a • Atomic Structure • Explain Atomic Line Spectra, Galaxies, etc. • Shapes of Orbitals in Atoms for Bonding • Ionization Energies and Trends in Chemical Reactivity (e.g., Li+ vs Li) • Which Molecules are Likely to Exist and Their Shapes and Reactivities (Ozone, Glo. Warm.) • Magnetic and Bonding Properties of Molecules (Magnetic Tapes, Disks, etc.) • Special Properties of Resonance Stabilization • Directionality of Covalent Chemical Bonds • Bonding in Solids XII-2
