Alternative periodic tables quantum numbers of the electron configuration, hence it has a four-dimensional base. In Theodor Benfey's periodic table (1964), the elements form a two-dimensional spiral, starting from hydrogen, and folding their way around two peninsulars, the transition metals, and lanthanides and actinides. A superactinide island is already slotted in. The Chemical Galaxy (2004) is organized in a similar way. Timothy Stowe's physicist's periodic table is three-dimensional with the three axes representing the principal quantum number, orbital quantum number, and orbital magnetic quantum number. Helium is again a group 2 element. Paul Giguère's 3-D periodic table consists of 4 connected billboards with
The Periodic Table (Basher book) get people engaged is to make it accessible while still presenting hard facts and knowledge," while Basher was concerned that the book's design be "sharp and focused" in order to "connect with today's visually advanced young audience." "Publishers Weekly" said that the book was a "lively introduction to the chart that has been the bane of many a chemistry student", and in a review in "New Scientist", Vivienne Greig called "The Periodic Table" "an engrossing read and an ideal way to painlessly impart a great deal of science history to seen-it-all-before teenagers."
