I need to know everything about the 13th element

Facts:

Aluminum is the 13th element in the Periodic Table and one of Earth's most abundant metals, and so is aluminum. Each atom of aluminum contains 18 protons. Aluminum atoms with fewer than 18 electrons are cations, while those with more than 18 electrons are anions.In 1884, the cap of the Washington Monument was made using aluminum because the metal was so highly valued at that time.Only 5% of the energy needed to purify aluminum from alumina is required to recycle aluminum from scrap. In fact, you can even recycle the element at home, if you like.

No its just makes the straight guy curious
