Which element is the most abundant metal in the Earth's crust?
Answer
Aluminum
Aluminum makes up about 8% of the Earth's crust by mass, making it the most abundant metal and the third most abundant element overall after oxygen and silicon. Despite this abundance, it was once considered more precious than gold because it was difficult to refine.

Aluminum was once so difficult to extract that Napoleon III reserved aluminum cutlery for his most honored dinner guests, while lesser guests ate with gold and silver utensils.
