Question

a shiny substance that conducts electricity in its solid state is most likely to be
a. an ionic compound.
b. a molecular compound.
c. a metallic element.
d. a nonmetallic element.

Explanation:

Ionic compounds conduct electricity when molten or in solution, not in solid state. Molecular compounds are poor conductors. Non - metallic elements are generally non - conductors. Metallic elements have delocalized electrons which allow them to conduct electricity in solid state and are often shiny.

Answer:

C. a metallic element.
