1. What is the element symbol?Al
2. What is the atomic number?13
3. What is aluminum and why is it so light?Aluminum is a metal that is very light because its density is only about one-third that of iron or steel. This makes it easy to move and use in many things.
4. How does aluminum stay protected from rust?When aluminum touches air, it quickly forms a thin, tough layer of oxide that stops the metal from corroding. This natural protection keeps it looking shiny and safe.

Passivation: The formation of a protective surface layer that prevents further chemical reaction or corrosion.
Electrolytic Cell: A device used to carry out electrolysis, involving electrodes and an electrolyte.
Alloying Elements: Metals or non-metals added to a base metal to improve its properties.
Circular Economy: An economic system aimed at eliminating waste and the continual use of resources.
