Which lightweight, corrosion-resistant metal is the most abundant metallic element found in Earth’s crust?

Explanation

Aluminum is the most abundant metallic element found in Earth’s crust, and it is prized for being both notably lightweight and highly resistant to corrosion, since it naturally forms a thin, protective oxide layer on its surface when exposed to air. These properties make aluminum widely useful across many industries, including aircraft manufacturing, packaging like beverage cans, and construction materials. Despite its natural abundance, extracting usable aluminum metal from its ore requires a considerable amount of energy, which is part of why recycling aluminum is particularly valuable and energy-efficient compared to producing new aluminum.
