Which of the following is not a transition metal?

Which of the following is not a transition metal?

Step 1: Understand what a transition metal is. Transition metals are elements that have partially filled d orbitals.
Step 2: Look at the definition of an incomplete d subshell. This means that the d subshell does not have all of its possible electrons filled.
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).
Step 6: Since Zinc has a full d subshell, it does not meet the criteria of having an incomplete d subshell.
Step 7: Conclude that Zinc is not considered a transition metal.
