Which metal is most abundantly found on Earth’s surface?
Which metal is most abundantly found on Earth’s surface?
- Aluminium is at the top of the list, being the most abundant metal in the Earth’s crust, constituting 8.1% to 8.23% of the Earth’s crust mass. It is also the third most abundant element in the Earth’s crust, after oxygen at 46%, and silicon at 28%. Due to its high reactivity, aluminium does not exist naturally in its elemental form, but in compounds, mostly in the ore bauxite.
- Zinc: Zinc is far less common, ranking approximately 24th among elements in the crust with an abundance of only about 0.007% (70 ppm).
- Iron: While iron is the most abundant metal in the entire Earth (due to its concentration in the core), it is only the second most abundant metal in the Earth's crust, making up about 5.0% to 5.6% of its mass.
- Copper: Copper is a relatively scarce metal in the crust, making up less than 0.006% (60 ppm) of its mass, which is significantly less than aluminium.
