Giant Ionic Lattice

Ionic compounds have a giant lattice structure  of positive and negative ions, held in place by strong electrostatic attractionbetween the oppositely charged ions.

High melting point - requires a lot of energy to break bonds.

Conducts electricity when molten or aqueous - ions become mobile in solution so can carry electrical current.

Dissolves well in polar solvents - polar solvents, like water, attracts ions out of the lattice into solution

Here is an Example, NaCl.
