Solution: Which of the transition elements in the first transition series have anomalous electron configurations?

Solution: Which of the transition elements in the first transition series have anomalous electron configurations?

Problem

Which of the transition elements in the first transition series have anomalous electron configurations?

Solution

We’re being asked to determine which of the transition elements in the first transition series have anomalous electron configurations.

 

This is because most transition metals are found in the d-orbital. 


Remember that according to Hund's rule, electron orbitals that are degenerate (same energy)are first half-filled before they are totally filled.

  • But, for certain cases the d-orbital is more stable when totally filled or half-filled


Recall that there are exceptions that exist for (anomalous) electron configurations for some transition metals.
