Which element has the same number of electron shells as tungsten in parentheses W

Answer 1

Tungsten (W) has 6 electron shells. Any element that also has 6 electron shells will have the same number of electron shells as tungsten. An example of such an element is lead (Pb), which also has 6 electron shells. Other elements in the same period or below tungsten in the periodic table will also have the same number of shells.
