Which of the following sets is of coinage metals?
- A. \( C u, A g, A u \)
- B. \( Z n, \)Сд\( , \)Н \( g \)
- C. \( A u, A g, Z n \)
- D. \( L i, N a, K \)
Step-by-step solution
Coinage metals are traditionally copper (Cu), silver (Ag), and gold (Au), which have been historically used for coins due to their malleability, ductility, and resistance to corrosion. Option A lists these three elements. The other options contain metals not classified as coinage metals: B includes zinc, cadmium, and mercury; C includes zinc; D includes alkali metals.
