• The force of attraction between the opposite
  charges of ions in an ionic compound
• A transfer of electrons occurs
• Compound has a neutral charge

EX Magnesium Chloride

• ZERO NET CHARGE

5
Covalent Bond

• The attraction that forms between atoms when they
  share electrons
• Molecule A neutral particle that forms as a
  result of electron sharing

6

• Single Covalent Bond

• Multiple Covalent Bond

7
Polar vs. Nonpolar

• Polar Molecule ? A molecule that has a slightly
  positive and a slightly negative end
• Nonpolar Molecule ? A molecule where electrons
  are shared equally in bonds
