Asked by julie

A substance conducts an electric current when it is in the liquid state. What would the conductivity of the substance in solid form indicate about the type of bond in the substance?
If the solid is conductive, the bonds are ionic.
If the solid is not conductive, the bonds are covalent.
If the solid is conductive, the bonds are metallic.
If the solid is not conductive, the bonds are metallic.

Correct answer: "If the solid is conductive, the bonds are metallic."

Reason: Metallic solids have delocalized electrons and conduct electricity in the solid state. Ionic compounds conduct when molten (ions mobile) but not as solids (ions fixed in the lattice), so if the substance conducts only when liquid and the solid does not conduct, that indicates ionic bonding (not covalent). Covalent/molecular substances typically do not conduct in either state.
