Which of the following has an incomplete d-subshell?
Correct Answer: Chromium (Cr)
- Step 1: Understand what a d-subshell is. The d-subshell can hold a maximum of 10 electrons.
- Step 2: Know the electronic configuration of elements. This tells us how many electrons are in each subshell.
- Step 3: Look at the electronic configuration of Chromium (Cr). It is [Ar] 4s1 3d5.
- Step 4: Identify the d-subshell in the configuration. In Chromium, the d-subshell is 3d.
- Step 5: Count the electrons in the d-subshell. Chromium has 5 electrons in the 3d subshell.
- Step 6: Determine if the d-subshell is complete. Since the maximum is 10 electrons and Chromium has 5, the d-subshell is incomplete.
