Which metal is described as soft, steel-white, tarnish-resistant and occurs naturally with platinum?

• A. Palladium
• B. Platinum
• C. Porcelain
• D. Restorative

Answer: (A)

The trait set points to palladium. Palladium is a member of the platinum group metals and has a bright steel-white luster. It is softer than platinum, which is a key clue here, yet it remains highly resistant to tarnish. In nature, palladium is commonly found in the same ore deposits as platinum, so it’s described as occurring with platinum. The other options aren’t metals or don’t match the “soft, steel-white, tarnish-resistant” description. Porcelain is ceramic, and restorative isn’t a metal, while platinum itself is harder and doesn’t fit the “soft” cue as well.
