Explanation

Gold does occur in its pure form (nuggets, flakes), but in practical applications, it is most commonly encountered as an alloy. Pure gold (24 karat) is too soft for most uses, so it is alloyed with other metals like copper or silver to increase durability. Brass and bronze are alloys, not pure elements. Copper is commonly found in pure form.
