For \(n=3, \ell=1\): This specifies the entire 3p subshell (all three 3p orbitals combined). Wait — the question asks about a single orbital (\(n=3, \ell=1\) without specifying \(m\)) or the subshell? If subshell: \(2\ell+1=3\) orbitals × 2 = 6 electrons. If a single orbital: 2 electrons. The answer key shows 2, implying it refers to a single orbital (one specific 3p orbital). Each orbital holds exactly 2 electrons.
