Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 (but was element  on the periodic table), a month after Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom were exactly equal to its place in the periodic table (also known as element number, atomic number, and symbolized Z).
