Quiz on Almunium element

Aluminium is a silvery-white, lightweight metal that is the most abundant metal in the Earth’s crust. It has the chemical symbol Al and an atomic number of 13. Aluminium is well-known for its remarkable combination of properties — it is strong, durable, non-magnetic, and highly resistant to corrosion due to a thin oxide layer that forms naturally on its surface. This makes it an excellent material for a wide range of uses, including aircraft parts, kitchen utensils, electrical cables, and packaging materials like foils and cans. The primary source of aluminium is the ore bauxite, from which it is extracted using the Bayer and Hall-Héroult processes. In addition to its industrial importance, aluminium is also used in alloys such as duralumin and magnalium to enhance strength and reduce weight. Its recyclability and abundance make it an eco-friendly and essential metal in modern industries.
