Today, the periodic table has 118 different elements, and has undergone extensive changes since Mendeleev’s first version. And as these elements were found, the periodic table expanded. Mendeleev’s original table was incomplete, but was such a powerful scientific tool that it was able to predict the weights and other properties of yet-to-be discovered elements. As early as 1869, Russian chemist Dimitri Mendeleev began arranging the then-known elements by atomic weight, creating what we now call the periodic table. By 1809, at least 47 were known, and by the mid-1800’s, naturalists were attempting to organize them. As early as 1669, naturalists began to discover individual elements.
