Periodic Table Dmitri Mendeleev / The Periodic Table Of Elements - The modern periodic table arranges elements by increasing atomic number.. It is at once evident that such regularities very much simplify the study of chemistry. Given the number of properties for each element and its many applications, how the table should look has long been a subject of debate. 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.

In the lower table the alkali metals have been raised from the bottom of the table and placed figure 1: Chemical 'groups' are now shown vertically in contrast to their horizontal format in mendeleev's table. Credit is given to dmitri mendeleev, a professor of chemistry in st. Groups from i to vii are meant for normal elements and group viii is for. 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.
Sendus your suggestions so we can make it better. 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.
