I believe copper is the best example because it definitely conducts electricity: most power cords are made with it. It conducts heat, i don't have a house hold reason, but it does. Copper is malleable, and ductile. Zinc and magnesium ribbon are too brittle. The problem with gold jewelry is that it is an alloy (which means that it is mixed with other metals, so it isn't pure gold). Aluminum foil is highly oxidized, so we aren't really talking about aluminum, (well, we are, but it's though to explain). The pennies are alloys also and usually dirty so they lose their metallic sheen which is one more metallic property.

Hi. My opinion? Gold, because it is the best example of a malleable material, conducts electricity (demonstrating free electrons in its outer electron cloud), and is shiny

these metal has different characteristics, and their usage are different, so we can not easily say which one is best. if it is used appropriately, it is the best

these are all metals so they will exhibit properties of metals.
