Question
Which electron configurations do not follow the Hund's rule?
A. I and II only
B. I and III only
C. II and III only
D. I, II and III
Markscheme
C
Examiners report
Many G2s and OCC forum comments were made by teachers as reference had been made to the Aufbau principle instead of just Hund´s rule. This was however no problem for the students as 88% recognised that options II and III are incorrect electron configurations.
