Periodic Table, Electronic Configurations, Ionic Bond

  • Look at overall shape of periodic table

  • Periods and groups

  • Group names; alkali metals(1A); alkaline earths(2A); halogens(7A)

  • Learn significance of s, p, d, f

  • Do examples of building up electronic configurations of atoms and monatomic ions including transition metals

  • Look at how atomic sizes change around the periodic table

  • Positive ions smaller than parent atom; negative ions larger than parent atom

  • “Magic numbers” of electrons in noble gases show stability

  • Ionization energies and how they change around the periodic table

  • Electron affinity – important only for most electronegative elements, halogens, O, S.

  • Characteristics of ionic compounds – crystalline, high m.p., conductors; electrostatic nature of ionic bond.
