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 tin as the main additive. d. it is very ductile and malleable, slightly harder than gold. please select the best answer from the choices provided a b c d

Explanation:

Silver is a pure element (Ag), not a copper alloy. Copper alloys include bronze (Cu-Sn) or brass (Cu-Zn). Other options correctly describe silver's properties: highest electrical conductivity, precious metal use, and ductility/malleability.

Answer:

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