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.
