The periodic table dates back to around 1870 when the Russian chemist D. Mendeleev used the similarities in chemical reactivity attributed to different elements to group them according to increasing atomic mass. The Periodic Table of the Elements is a tabular method of displaying the chemical elements. The differences in chemical reactivity between the elements are based on the number and spatial distribution of an atom’s electrons. The periodic table of elements arranges all of the known chemical elements in an informative array.
