What holds together an ionic bond? | The strong electrostatic forces of attraction between oppositely charged ions |
Why can ionic compounds not conduct electricity in the solid state? | The ions are in fixed positions within the lattice and are unable to flow freely |
Ionic compounds can conduct electricity when in the _____________ or in ____________ | molten state, solution |
Why can ionic compounds conduct electricity when in the molten state or in solution? | Because they have ions that can move and carry charge |
What is the structure of an ionic compound called? | A lattice |
Name 3 properties of ionic compounds | 1. High strength bonds 2. High melting and boiling points 3. Conduct electricity when liquid |
Why do ionic compounds have high melting and boiling points? | Ionic bonds are very strong, and a high amount of energy is required to break the bonds. |
