Copper and gold are not malleable in nature.
Malleability: It is the ability of a substance to be beaten into thin sheets.
Hence, the given statement is false.
Consider the following materials :
Copper, Sulphur, Phosphorous, Carbon (such as pencil head), Gold, Silver.
Which of these materials is:(i) malleable and ductile, and (ii) brittle?
Metals are not malleable.
Even copper and aluminium are malleable and ductile. So why are they not used to make jewellery? Can we say because gold and silver don't react with oxygen and water and so they don't corrode our skin.
