Which of the following is not true of silver?

Question

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.

Answer 1

The statement that is not true of silver is:

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

Silver is a distinct metal, not an alloy of copper or tin. While silver can be alloyed with other metals (such as copper in sterling silver), it is not accurate to say that it is a copper alloy.
