QUESTION:
Pure gold is so soft?
ANSWER:
A. The chemical element gold is classed as a transition metal.
HARD EXPLAIN:
Although it is very strong, gold is the most malleable of all metals. Pure gold is too soft to withstand the stresses of everyday wear, so it is combined with different alloys to give it strength and durability. ... Even though 24kt is pure gold, it is extremely soft and not recommended for jewelry.
