Web4 de mai. de 2012 · Many people tried to arrange a proper periodic table but the first periodic table was given by Dimitry Ivanovich Mendeleev. But it was later modified by Henry Mosley in its present form. WebHow was the periodic table arranged by Mendeleev? In his periodic table, Mendeleev arranged elements in rows by increasing atomic mass. Within a row, elements with lower atomic masses were on the left. Mendeleev started a new row every time the chemical properties of the elements repeated. Thus, all the elements in a column had similar …
