Webeight elements in the periodic table. 1. Introduction. It is an amusing sidelight of history of science that the original names used by Mendeleev. for gallium and germanium are eka-aluminum and eka-silicon, where the eka, Sanskrit. for one, has the sense of beyond. The prediction for the existence of these elements was. WebScientists use the periodic table for quick references to information about an elements. The periodic table helps scientists understand how elements behave and react to one another. Dmitri Mendeleev and Henry Moseley were scientists who each contributed greatly to the periodic table we use today.
