Periodic Trends Atomic radius decreases Ionization energy increases Electronegativity increases Ionization energy decreases Electronegativity decreases Atomic radius increases 1 2 3 4 5 6 7 8

Which of the following has the largest atomic radius: P, S, Cl or As Which of the following has the largest atomic radius: P, S, Cl or As? BONUS…Which is larger K or K+? Arsenic

ITS SHAPE! (or Molecular Geometry) Valence Shell Electron Pair Repulsion Theory predicts what about a molecule? ITS SHAPE! (or Molecular Geometry) BONUS… What shape is shown here? (5,0) BA5

Does phosphorus tribromide have a dipole moment? If so, can you draw it? (4,1) Trigonal pyramidal Yes it does! Why? Because one side of the m’c is a lot more negative than the rest of the m’c. Polar m’c w/3 polar bonds!

Draw a proper Lewis structure for carbonmonofluoridetrichloride (and no, we won’t be using clickers for this ) C Cl F Cl

Is carbonmonofluoridetrichloride an ionic, polar or nonpolar molecule Is carbonmonofluoridetrichloride an ionic, polar or nonpolar molecule? (and yes, we will be using clickers for this ) POLAR! C Cl F Cl

Is carbontetrachloride an ionic, polar or nonpolar molecule Is carbontetrachloride an ionic, polar or nonpolar molecule? (and yes, we will be using clickers for this ) NONPOLAR! C Cl Cl Cl
