Graphic representation of the periodic table of chemical elements organized as a left-step series table with Group 0 positioned on the right side of the table and Group Ia (Li and Na) placed above the elements of Group Ib (Cu, Ag, and Au) . This table was originated by Russian chemist and inventor Dmitri Ivanovich Mendeleev (1834-1907) in 1871 and classified by chemist Edward G. Mazurs as Type IIC2-1 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This illustration appears as Figure 47 on page 121 of Mazurs' 1957 publication.
