Answer 1

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

From the provided options:

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

The correct response is **gold (Au)**, as it is in the same period (6) as tungsten (W) and thus has the same number of electron shells.
