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
