Q: Which of the following elements has an incomplete d subshell?
Solution:
Chromium (Cr) has an electronic configuration of [Ar] 4s1 3d5, which means it has an incomplete d subshell.
Steps: 6
Show Steps
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.
