Which term describes elements that are good conductors of heat and electric current?

• A. Physical Change
• B. Metal
• C. Reactant
• D. Product

Answer: (B)

Metals are the category described by good conductors of heat and electric current. This happens because metallic bonding creates a lattice of positive ions in a “sea” of delocalized electrons that can move freely. Those mobile electrons carry electrical charge and transfer energy quickly, so metals conduct both electricity and heat well. The other terms don’t address a material’s conductive properties: a physical change is about changing state or appearance without changing composition, while reactant and product refer to substances involved in a chemical reaction. So the correct term is metal.
