(WCSU24) The cross sections of three different ionic compounds (labeled Compound 1, 2 and 3) are displayed in the figures below. In the figures, the charge on each ion is indicated, and the diameter of each circle reflects the diameter of each ion. Rank these compounds in order of increasing melting point. lowest [drop1] < [drop2] < [drop3] highest
