1. Properties of Ionic and Covalent Bonds
Section 6-1 continued

2. Ionic Bonds Covalent Bonds
High melting points
Usually solids at room temperature
Good conductors when dissolved in water
Dissolve in water and other polar compounds
Low melting points
Gas or liquids at room temperature
Poor conductors
Polar covalent compounds dissolve in water and other polar compounds. Nonpolar covalent compounds do not dissolve in water and other polar compounds

3. Polyatomic Ions
More than one atom bonded by covalent bonds but still have an overall charge.
Form ionic bonds with an ion of opposite charge.
