Select three properties that ionic compounds have:

High Melting and Boiling Points: Ionic compounds have high melting and boiling points because the ionic bonds that hold the ions together are very strong. It takes a lot of energy to overcome these bonds and change the compound from a solid to a liquid or a gas.

Electrical Conductivity: Ionic compounds can conduct electricity, but only when they are dissolved in water or melted. In these states, the ions are free to move, which allows them to carry electrical charge.

Solubility in Water: Most ionic compounds are soluble in water. The polar water molecules are able to surround the individual ions and pull them away from the crystal lattice, causing the ionic compound to dissolve.
