Tungsten (W) has an atomic number of 74 and is located in period 6 of the periodic table, which means it has 6 electron shells.
To determine which element has the same number of electron shells as tungsten, we can look at the options provided:
- Gold (Au) is in period 6, so it has 6 electron shells.
- Nickel (Ni) is in period 4, so it has 4 electron shells.
- Yttrium (Y) is in period 5, so it has 5 electron shells.
- Molybdenum (Mo) is in period 5, so it also has 5 electron shells.
Therefore, the correct answer is gold (Au), as it has the same number of electron shells (6) as tungsten.
