He formulated the periodic law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the. The heading reihen means row and the heading gruppe means group. While dmitri mendeleev is most often cited as the inventor of the modern periodic table, his. 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.

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. Petersburg, his students carried a large copy of the periodic table of the elements as a tribute to his work. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements.
