Question

which of the following is not true of silver? a. it has the highest electrical conductivity of all metals. b. it is a precious metal used to make ornaments, jewelry, and utensils. c. it is a copper alloy, usually mixed in as the main additive. d. it is very ductile and malleable, slightly harder than gold. please select the best answer from the choices provided

Explanation:

Silver is a pure element (Ag), not a copper alloy. Copper alloys like bronze (copper-tin) or brass (copper-zinc) exist, but silver itself is not an alloy. Other options are true: silver has highest electrical conductivity, is a precious metal for ornaments, and is ductile/malleable harder than gold.

Answer:

C. It is a copper alloy, usually mixed tin as the main additive.
