The Ionic Bond | Boundless Chemistry - Lumen Learning
At the macroscopic scale, ionic compounds form lattices, are crystalline solids under normal conditions, and have high melting points. Most of these solids are soluble in H 2 O and conduct electricity when dissolved. The ability to conduct electricity in solution is why these substances are called electrolytes.Table salt, NaCl, is a good example of this type of compound.
