Mendeleev was the inventor of the periodic table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence â¦ of elements that had not yet been discovered based on gaps in the table he created.
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
