Which of the following elements 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 that an incomplete d subshell means that the d subshell does not have all 10 electrons.
- Step 3: Look at the electronic configuration of the elements given in the question.
- Step 4: Identify the electronic configuration of Chromium (Cr), which is [Ar] 4s1 3d5.
- Step 5: Analyze the 3d part of the configuration. Since it has 5 electrons, it is not full (incomplete).
- Step 6: Conclude that Chromium (Cr) has an incomplete d subshell.
