검증된 단계별 안내1
Understand the concept of metallic bonds: Metallic bonds are the force of attraction between free-floating valence electrons and positively charged metal ions. These bonds are characteristic of metals.
Identify the substances given in the problem: Carbon dioxide (CO2), Sodium chloride (NaCl), Copper (Cu), and Water (H2O).
Recognize that metallic bonds are typically found in pure metals or alloys, where metal atoms are closely packed and share a 'sea' of electrons.
Analyze each substance: CO2 is a molecular compound with covalent bonds, NaCl is an ionic compound, and H2O is a molecular compound with covalent bonds.
Conclude that Copper (Cu), being a pure metal, contains metallic bonds, as it consists of metal atoms sharing a 'sea' of delocalized electrons.
