Tungsten (W) has 6 electron shells. Any element that also has 6 electron shells would be in the same period or a neighboring period of the periodic table. An example of an element that also has 6 electron shells is lead (Pb), which is located in the same period (Period 6) as tungsten. Other elements in that period include barium (Ba), mercury (Hg), and platinum (Pt).
