Web11 de abr. de 2024 · He introduced a law that stated that the properties of a given element are the periodic function of their atomic masses. He then arranged elements in periods or horizontal rows and groups or vertical columns in increasing order according to their atomic weights. The vertical column contains the elements which have similar properties. WebRussian chemist Dmitri Mendeleev produced a periodic table based on atomic weights but arranged ‘periodically’. Elements with similar properties appeared under each other. … crystal goins
