It takes a large amount of mechanical force, such as striking a crystal with a hammer, to force one layer of ions to shift relative to its neighbor. Answer: B. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. This generates that they become good conductors when molten, since the ions are free to move through the liquid and thus can carry an electric current. The process of melting an ionic compound requires the addition of large amounts of energy in order to break all of the ionic bonds in the crystal. To describe the physical properties of ionic compounds. The regular and orderly arrangement of ions in the crystal lattice is responsible for the various shapes of these crystals, while transition metal ions give rise to the colors. table salt (NaCl melts at 1714 degrees fahrenheit, while CH4 melts at -295 degrees fahrenheit).
