Charles Janet (French: [ʃaʁl ʒanɛ]; 15 June 1849 – 7 February 1932) was a French engineer, company director, inventor and biologist. He is also known for his left-step periodic table of chemical elements.
This form of periodic table is congruent with the order in which electron shells are ideally filled according to the Madelung rule, as shown in the accompanying sequence in the left margin (read from top to bottom, left to right). The experimentally determined ground-state electron configurations of the elements differ from the configurations ...

Mazurs provided a comprehensive analysis and classification of periodic tables, listing and classifying over 700 periodic tables. [3] He recommended Charles Janet's left-step system and suggested that it could be expanded into three dimensions. [4]

Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity.
