Which of these is a coin metal?
Think it through first, then pick an option.
- a Pt
- b Al
- c Zn
- 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.
