Classical Periodic Table

[A diagram in the shape of the periodic table of elements is split into labeled colored regions. Each region is labeled with a large letter over a word in smaller letters.]

[The regions and colors are as follows:]

  • A: Air: light blue: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, and the noble gases.
  • W: Water: dark blue: Bromine and Mercury.
  • F: Fire: red-orange: Astatine, Francium, and everything from Nobelium onwards (radioactive).
  • E: Earth: brown: everything else, covers majority of the diagram.

Personally I think mercury is more of a 'wet earth' hybrid element.
