Ionic compounds have high melting points.
This can best be explained by the fact that the bonds in ionic compounds
A. involve the sharing of electrons.
B. require a great deal of energy to break.
C. occur between metals and nonmetals.
D. form between a positively charged atom and a negatively charged atom.
Most ionic compounds exist as solids at room temperature. In order to melt or boil an ionic compound, the ionic bonds must be broken. It takes a great deal of energy to break an ionic bond. For this reason, ionic solids have high melting and boiling points.
