General metallurgy: Identify the most malleable metal among common metals. Malleability refers to the ability of a metal to be hammered into thin sheets without breaking. Choose the correct metal.

Difficulty: Easy

Iron
Platinum
Gold
Aluminium
Copper

Correct Answer: Gold

Explanation:

Concept

Malleability = ability to be hammered/rolled into sheets.
Gold > Silver > Aluminium ≈ Copper ≫ Iron for malleability.

Reasoning
Gold can be beaten into extremely thin leaf (∼0.1 µm), making it the most malleable common metal.

Final Answer
Gold.
