Question

why do industries use metallic compounds to make wires? (select all that apply) metallic compounds are ductile due to the free - moving electrons that allow the metal nuclei to roll over each other; thus, they are able to be re - shaped into thin wire. metallic compounds are malleable because of the rigid lattice structure formed between the metal nuclei; thus, metal wires permit energy to move through them while remaining solid wire. metallic compounds are good conductors of electricity because of the free - moving electrons shared between the metal nuclei; this allows electrical current to flow within the wire. metallic compounds often have high luster because of the photoelectric effect; therefore, they make for shiny wires.

Explanation:

• First option: Metallic compounds are ductile (ability to be drawn into wires) because of the free - moving electrons. The free electrons allow the metal nuclei to roll over each other during the wire - making process (ductility).
• Second option: Malleability (ability to be hammered into sheets) is related to the structure, but the statement about the reason for energy movement is incorrect. The main reason for electrical conductivity (related to energy movement as electricity is a form of energy) is the free - moving electrons, not the rigid lattice for conductivity in the context of wires.
• Third option: Metallic compounds have free - moving electrons (sea of electrons) which are responsible for their electrical conductivity. This property is crucial for wires as wires need to conduct electricity.
• Fourth option: High luster (shininess) is due to the interaction of light with the free - moving electrons, but luster is not a functional property for why wires are made. Wires are made for electrical conductivity and the ability to be shaped (ductility), not for their shine.

Answer:

• First option: Metallic compounds are ductile due to the free - moving electrons that allow the metal nuclei to roll over each other; thus, they are able to be re - shaped into thin wire.
• Third option: Metallic compounds are good conductors of electricity because of the free - moving electrons shared between the metal nuclei; this allows electrical current to flow within the wire.
