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 Fifth Element was a play on information in the periodic table. Rubidium is the first of the Period 5 elements, and exactly halfway down that row is the element Rhodium. Taking the first half of each element yields "Rubi Rhod". Others have speculated his name is a play on his gender bending personality; having a feminine first name and phallic surname. Three different teams handled the three different types of special effects used in the film. Nick Allder was placed in charge of mechanical and pyrotechnical effects, Nick Dudman was placed in charge of 'creature' effects and Mark Stetson headed the visual
