Which orbital diagram for carbon's 2p subshell is correct (arrows represent electrons)?
A.↑ ↑ in two separate 2p orbitals
B.↑↓ in one 2p orbital
C.↑↓ ↑↓ in two 2p orbitals
D.↑ ↑ ↑ in three 2p orbitals
Explanation
Core Concept
Carbon's 2p² electrons occupy two different orbitals with parallel spins per Hund's rule. Pairing would cost repulsion energy, so unpaired placement wins.
Correct Answer
A↑ ↑ in two separate 2p orbitals
