Out of these which is the most abundant metal found in the earth's crust ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Aluminium
Aluminium is the most abundant metal in the earth’s crust, about 8% by mass; only oxygen and silicon, both non-metals, are more abundant. It is found mainly in bauxite and in clays and other silicate minerals.
Iron comes next among the metals (about 5%); copper and zinc are far less common.
