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 include bronze (Cu-Sn) or brass (Cu-Zn). The other options correctly describe silver's properties (highest conductivity, precious metal use, ductility/malleability).

Answer:

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