Question: Which of the following elements is not a transition metal?

Options:

Correct Answer: Zinc (Zn)

Solution:

Zinc (Zn) is not considered a transition metal because it does not have an incomplete d-subshell in its elemental state.

Which of the following elements is not a transition metal?

Which of the following elements is not a transition metal?

Step 1: Understand what transition metals are. Transition metals are elements that have partially filled d-orbitals in their atomic structure.
Step 2: Look at the periodic table and find the transition metals. They are located in groups 3 to 12.
Step 3: Identify the element in question, which is Zinc (Zn).
Step 4: Check the electron configuration of Zinc. It is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s².
Step 5: Notice that in its elemental state, Zinc has a full d-subshell (3d¹⁰), meaning it does not have any unpaired electrons.
Step 6: Conclude that since Zinc does not have an incomplete d-subshell, it is not classified as a transition metal.
