Ionic solids are one common type of solids. In an ionic solid, the atoms are mostly in ionic form, and the ions are held together by the electrostatic attraction between the ions. Common properties of ionic substances are:
  • High melting point and boiling point. Ionic bonds are strong.
  • Soluble in polar solvents such as water. The ions have favorable interactions with the polar solvent and thus it takes less energy to remove them from the crystal
  • Poor electrical conductivity. The electrons are localized around the ions, not spread out like in a metal.
