Which of these is a coin metal?

Think it through first, then pick an option.

  1. a Pt
  2. b Al
  3. c Zn
  4. d Au
Answer and explanation

Correct answer: d Au

Au (gold) is a group 11 coin metal, used for coins in ancient times.

Why the other options are wrong

  • a Pt: Pt is not on the list of coin metals; the coin metals are Cu, Ag and Au of group 11. The answer is Au.
  • b Al: Al is a group 13 metal, not a coin metal. The answer is Au.
  • c Zn: Zn is in group 12, not group 11. The answer is Au.
