Aluminum is a chemical element, meaning it's made up of only one type of atom. It's not made "out of" anything else in the way that a cake is made out of flour, sugar, and eggs.

Here's a breakdown:

* Aluminum is the name of the element itself, represented by the symbol "Al".

* Aluminum atoms are the building blocks of aluminum. These atoms contain 13 protons, 13 electrons, and usually 14 neutrons.

So, to answer your question directly, aluminum is made out of aluminum atoms.
