Metals behave in unique ways. The bonding that occurs in a metal is responsible for its distinctive properties: luster, malleability, ductility, and excellent conductivity. Q: Luster, malleability, ductility, and conductivity are all properties of which kind of material? Choices: - ores - wood - nonmetals - metals A:
A: metals
