Mendeleev's periodic table of 1869 seems all the more remarkable when we consider his relative isolation from the main centers of chemical research in western europe, and the rather naive attempts made by scientists in those centers to bring some sort of order to the growing list of chemical elements. This note presents reasons why mendeleev chose sanskrit names (now superseded) for eight elements in the periodic table. Reading the modern periodic table our modern day periodic table is expanded beyond mendeleev's initial 63 elements.

In 1869, mendeleav, a russian chemist made a thorough study of the relation between the atomic weights of the elements and their physical and chemical properties. Most of the current periodic tables in other words the elements of what we now call a period were listed vertically by mendeleev. This can take up to four minutes.
