Ionic Bonds worksheet with exercises and a table for learning about ionic compounds.

- Ionic bonds form between metals and nonmetals.
- In naming simple ionic compounds, the cation is always first, the anion second (e.g., sodium chloride).
- Ionic compounds dissolve easily in water and other polar solvents.
- In solution, ionic compounds easily conduct electricity.
- Ionic compounds tend to form crystals with high melting temperatures.

Naming Ionic Compounds:
- Write the cation first and the anion second.
- Use subscripts to indicate the number of atoms of each type present in the compound.
- No prefixes.
- Change the ending of the anion to say -ide.
