 * Common Misconceptions**
 * Molecules can contain metals.
 * There are no limitations of this bonding model.
 * Ionic pairs, such as Na+ and Cl-, are molecules.
 * A very common misconception about dissolving:

 * Interesting Facts:**
 * All ionic compounds form crystals.
 * They are very hard and brittle.
 * Bones are able to support our bodies because they contain calcium phosphate, an ionic compound.
 * They conduct electricity in the molten state but not in the solid state.
 * They have high melting points.
 * This bonding model doesn't explain why different ionic compounds form different crystal shapes (e.g. some are cubic and others are needle-like).
 * The differences in solubility of some ionic substances cannot be explained by the bonding model.
