element and actinide

This central charge would thus be approximately half the atomic weight ( though it was almost 25 % off the figure for the atomic number in gold ( Z = 79, A = 197 ), the single element from which Rutherford made his guess ).
Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 ( but was element Z = 79 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 was exactly equal to its place in the periodic table ( also known as element number, atomic number, and symbolized Z ).
