Use the periodic table to answer the question. Which element has the same number of electron shells as tungsten (W)? (1 point) Responses nickel (Ni) nickel (Ni) molybdenum (Mo) molybdenum (Mo) yttrium (Y) yttrium (Y) gold (Au) gold (Au)

Molybdenum (Mo) has the same number of electron shells as tungsten (W).

Use the periodic table to answer the question. Which element is a noble gas? (1 point) Responses fluorine (F) fluorine (F) hydrogen (H) hydrogen (H) radon (Rn) radon (Rn) rubidium (Rb)

Radon (Rn) is a noble gas.

Use the periodic table to answer the question. Which statement about nitrogen (N) and phosphorus (P) is correct? (1 point) Responses They have the same number of valence electrons. They have the same number of valence electrons. They have the same number of electron shells. They have the same number of electron shells. They are both inert. They are both inert. They are both classified as halogens.

The correct statement about nitrogen (N) and phosphorus (P) is that they have the same number of valence electrons.

To determine the element that has the same number of electron shells as tungsten (W), we need to find its position on the periodic table. Tungsten is located in Group 6 and Period 6 of the periodic table.

To find an element with the same number of electron shells, we look for an element in Period 6. The options provided are: nickel (Ni), molybdenum (Mo), yttrium (Y), and gold (Au).

Out of these options, only molybdenum (Mo) is located in Period 6 of the periodic table. Therefore, molybdenum (Mo) is the element that has the same number of electron shells as tungsten (W).

To find the element that has the same number of electron shells as tungsten (W), we need to determine the number of electron shells in tungsten first.

Tungsten (W) is located in the periodic table with an atomic number of 74. To determine the number of electron shells, we look at its electronic configuration. The electronic configuration of tungsten is [Xe] 4f^14 5d^4 6s^2.

Here, the highest energy level is 6, which corresponds to the sixth period in the periodic table. Therefore, tungsten has six electron shells.

Now, let's go through the options given to see which element has the same number of electron shells as tungsten:
1. Nickel (Ni) is located in the fourth period, so it has four electron shells. It does not have the same number of electron shells as tungsten.
2. Molybdenum (Mo) is located in the fifth period, so it has five electron shells. It does not have the same number of electron shells as tungsten.
3. Yttrium (Y) is located in the fifth period, so it has five electron shells. It does not have the same number of electron shells as tungsten.
4. Gold (Au) is located in the sixth period, so it has six electron shells, same as tungsten.

Therefore, the correct answer is gold (Au).
