User:TyEvSkyo/Two-dimensional spiral (Benfey, 1964)

Benfey's Two-Dimensional Spiral is an alternate model to the periodic table, where the elements start from hydrogen and go outward, forming the following pennensulars: Transition Metals, Lanthanides and Actinides, as well as Superactinides.^[1]

History[edit]

Benfey developed this form of the Periodic Table while he was the editor of the ACS chemical education magazine, "Chemistry".^[2]^[3] It has been used in at least two textbooks. ^[3]
