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
editBenfey 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]
