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 (short story collection) The Periodic Table (short story collection) The Periodic Table () is a collection of short stories by Primo Levi, published in 1975, named after the periodic table in chemistry. In 2006, the Royal Institution of Great Britain named it the best science book ever. The stories are autobiographical episodes of the author's experiences as a Jewish-Italian doctoral-level chemist under the Fascist regime and afterwards. They include various themes that follow a chronological sequence: his ancestry, his study of chemistry and practising the profession in wartime Italy, a pair of imaginative tales he wrote at that time, and his subsequent experiences
