Sodium chloride is an ionic compound that has a crystalline structure. Each sodium ion (Na+) interacts with 6 chloride ions (Cl-) on each side of it, and each Cl- interacts with the 6 Na+ around it. In a single salt crystal, there are millions and millions of ionic bonds. To melt an ionic material, we need to break each of those ionic bonds. Ionic bonds are not that weak, and when we try to break all of them it takes a lot of energy!
