Graphic representation of the periodic table of chemical elements designed as a series table with Group 0 placed in the middle of the table. This table was originated by Curt Schmidt in 1918 and classified by chemist Edward G. Mazurs as Type IIC2-5 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This table appears as Figure 55 on page 126 of Mazurs' 1957 publication.
