Periodic Table Dmitri Mendeleev / Mendeleev S Periodic Table 1891 Author Dmitri Mendeleev Flickr : The symbols r2o and rh4, etc., are written in the style of the time which uses superscripts to denote the number of.. Today's periodic table today's periodic table is a modification of mendeleev's periodic table. The noble gases (helium, neon, argon etc.) were not discovered until much later, which explains why there was a periodicity of 7 and not 8 in newlands table. This table shows the form of mendeleev's periodic table of the chemical elements as published in 1872. The periodic table of elements was designed independently about the same time by two different scientists. The periodic table of chemical elements (abbreviated periodic table) is well known to anyone who has ever entered into the scientific laboratory or classroom.
