Tungsten (W) is in period 6 of the periodic table, which means it has 6 electron shells. To find which element has the same number of electron shells, we need to look for an element that is also in period 6.

  • Molybdenum (Mo) is in period 5.
  • Yttrium (Y) is in period 5.
  • Gold (Au) is in period 6.
  • Nickel (Ni) is in period 4.

Therefore, the element that has the same number of electron shells as tungsten (W) is gold (Au).
