Question

vanadium orbital notation and condensed orbital notation​

Answer 1

Answer:

Explanation:I am learning about electron configurations and I came across the "exceptions" of Cr and Cu where electrons actually half fill the d orbitals instead of the expected s orbitals. I thought maybe vanadium would do the same, but my textbook gives the answer of an electron configuration exactly following the Aufbau principle.

I've attached a picture of my drawing for the textbook answer and what I had thought might happen — could someone explain why vanadium is not an "exception" like chromium or copper?
