2.1+Ionic+Compunds

__**2.1 Ionic Compounds.**__ An ionic compound consists of a giant structure of ions arranged in a lattice. The attractive electrostatic forces between the oppositely charged ions hold the structure together. This means ionic compounds have very high melting/boiling points. When enough energy separates the ions they become a liquid and can move more freely. This means that they can carry an electrical charge. But solid ionic compounds can not conduct electricity because they can not move around. Many ionic compounds can dissolve in water. When you dissolve an ionic compound in water the lattice is split up by the water molecules so the ions are free to move. This means that they will conduct electricity like a molten ion. The ions in the structure are then free to move around.
