The number listed below reflects just a couple of examples of the shade and brilliance of normally developing ionic crystals. The continuous and also orderly plan of ions in the crystal lattice is responsible for the assorted shapes of these crystals, while transition steel ions offer rise to the colors.
You are watching: Which one of the following properties is least characteristic of typical ionic compounds?
Another characteristic residential property of ionic compounds is their electrical conductivity. The figure below shows three experiments in which two electrodes that are connected to a light bulb are inserted in beakers containing 3 different substances.

In the initially beaker, distilled water does not conduct a current bereason water is a molecular compound. In the second beaker, solid sodium chloride also does not conduct a present. In spite of being ionic and thus created of charged pshort articles, the solid crystal lattice does not enable the ions to relocate in between the electrodes. Mobile charged pposts are required for the circuit to be finish and also the light bulb to light up. In the 3rd beaker, the (ceNaCl) has been dissolved right into the distilled water. Now the crystal lattice has been broken acomponent and also the individual positive and negative ions deserve to relocate. Cations relocate to one electrode, while anions relocate to the other, permitting power to circulation (watch number below). Melting an ionic compound also frees the ions to conduct a current. Ionic compounds conduct an electrical present as soon as melted or liquified in water.
