Question

According to Hund's rule, what is the lowest energy arrangement for electrons in degenerate orbitals?
Options
A Electrons paired together in the same orbital
B Electrons occupying separate orbitals with their spins unpaired
Correct Answer
C All electrons in the lowest energy orbital
D Electrons with opposite spins in the same orbital
Correct Answer

Detailed Explanation

For degenerate orbitals, the lowest energy is attained when the electrons occupy separate orbitals with their spins unpaired.

Hint

The notes describe this as the condition for lowest energy.
