Problem
A chemist concludes that sample Z is ionic after measuring its high melting point and its ability to conduct electricity only when molten. Which additional macroscopic observation would most strongly reinforce this conclusion?
(a) Z can be hammered into thin sheets without cracking.
(b) Z cleaves cleanly along flat planes when struck.
(c) Z dissolves readily in a nonpolar solvent such as hexane.
(d) Z conducts electricity well in the solid state.
