DeskTopper models of the
Chemical Element System / 3D Periodic Table
Two separate fully color coded student size Alexander Arrangement Periodic Table models assemble in minutes, providing an accurate view of the real Chemical Element System as well as a new and correct way of explaining the necessities and convenience of flat periodic table.
DeskToppers are printed on sturdy card stock: 4.75" tall inside a 7.5" circle when assembled (with either Y over Lu, or Y over La, or both).
The assembled model can be folded and flattened to 11.25" x 5" for portability in binders and folders.
