Title: Chemical Bonding


1
Chemical Bonding
  • The types of bonds a substance has influences its
    chemical and physical properties.

2
Covalent Bonds
  • Formed by the sharing of electrons
  • Typically between two nonmetals

3
Covalent Bond Properties
  • Weaker Attraction
  • Low Melting and Boiling Points
  • Often a gas at room temperature

4
Ionic Bonds
  • Formed by the transfer of electrons
  • Typically between metals and nonmetals
  • Cation and Anion
  • Polyatomic Ions

5
Ionic Bond Properties
  • Very Strong Attractive Force
  • Higher Melting and Boiling Points
  • Crystal Lattice Structure
  • Hard but brittle
  • Shifting of layers causes breakage
  • Often dissolve in water
  • Ionic solution is an electrical conductor

6
Metallic Bonds
  • Formed by the attraction of two metals
  • The attraction is between the metal and the sea
    of electrons
  • Lots of vacant orbitals that overlap so electrons
    can roam freely. (sea of electrons)

7
Metallic Bond Properties
  • Electrical Conductor in its solid state
  • Due to freely roaming electrons
  • Shiny Appearance
  • Absorbs a wide range of
  • frequencies of light
  • Malleable and Ductile
  • Bonding is the same in all directions
  • Layers can slide freely
