Graphic representation of the periodic table of chemical elements designed in the style of a so-called "periodic chain" with the numbers of valences for each element noted on the left-hand side. This table was originated by Russian chemist and inventor Dmitri Ivanovich Mendeleev (1834-1907) in 1889 and classified by chemist Edward G. Mazurs as Subtype IIIC1-1a in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This table appears as Figure 62 on page 131 of Mazurs' 1957 publication.</div>
1869 (Original design), Circa 1957 (Date attributed to slide)
