Have you not got anymore for us to ponder...?
Explanation:
Ionic bonding involves the interaction of discrete ions...they are marked by non-molecularity, and the formation of ionic substances that have high melting and boiling points. You should look up the melting points of each substance listed in order to appreciate this.
How do you know which is which? That proposition is a bit harder to address ...but I assure you that the melting points, and boiling points of the ionic materials will be quite elevated with respect to the non-ionic or molecular materials, ....the weakest ionic bond will occur for ammonium chloride, and its decomposition temperature will reflect this. In addition, there are many materials that ARE NON-IONIC, and NON-MOLECULAR, for instance diamond, or graphite, or silicon dioxide. Are these materials likely to have high or low melting or boiling points?
