Question

question 2. a solid sample of copper is an excellent conductor of electric current. which type of chemical bonds are in the sample?
○ ionic bonds
○ metallic bonds
○ nonpolar covalent bonds
○ polar covalent bonds

Explanation:

Copper is a metal. Metallic bonds involve a sea of delocalized electrons, which allow metals like copper to conduct electricity well. Ionic bonds are between ions (e.g., in salts), covalent bonds (polar/nonpolar) are between non - metals sharing electrons, and they don't have the free - moving electrons for good electrical conductivity like metallic bonds do.

Answer:

Metallic bonds (the option with "Metallic bonds" text)
