Chapter 9 Chemical Bonding I: PART 2

Chapter 9 Chemical Bonding I: PART 2. Ionic Bonding Model vs. Reality. Lewis theory: attractions btwn ions are strong ionic compounds should have high MPs & BPs (breaking down crystal should require lots of E ) stronger attraction (larger lattice E), higher the MP.

Periodicity

Periodicity. When one looks at the chemical properties of elements, one notices a repeating pattern of reactivities. Periodic Table. The rows on the periodic chart are periods. Columns are groups. Elements in the same group have similar chemical properties. Groups.

Percent Composition

Percent Composition. Example: MgO Find molar mass of whole compound: MgO = 24.3 + 16.00 = 40.3 grams % Mg (by mass) = mass of Mg = 24.3 g x 100 = 60.3% molar mass of MgO 40.3 g
