The figure listed below shows simply a few examples the the color and also brilliance the naturally emerging ionic crystals. The regular and orderly arrangement of ion in the crystal lattice is responsible for the assorted shapes of these crystals, while shift metal ions give rise come the colors.
You are watching: Which of the following is a characteristic of an ionic bond
Another characteristic residential or commercial property of ionic link is your electrical conductivity. The figure below shows 3 experiments in which 2 electrodes that are linked to a light pear are inserted in beakers containing three various substances.
In the first beaker, distilled water does not conduct a current due to the fact that water is a molecular compound. In the 2nd beaker, solid sodium chloride likewise does not conduct a current. Despite being ionic and thus created of fee particles, the solid crystal lattice does not permit the ions to move between the electrodes. Mobile charged particles are compelled for the circuit to it is in complete and also the light pear to irradiate up. In the 3rd beaker, the NaCl has actually been liquified into the distilled water. Currently the crystal lattice has actually been damaged apart and the individual hopeful and negative ions have the right to move. Cations move to one electrode, when anions move to the other, enabling electricity to circulation (see number below). Melting an ionic compound also frees the ions to command a current. Ionic compounds conduct an electric present when melted or dissolved in water. The dissolved of ionic compound in water will certainly be debated in section 9.3.What Is 0.5 As A Whole Number, Round To The Nearest Whole Number 0
NaCl(s) → Na+(aq) + Cl–(aq)
