Quizplus · Accepted Answer

Li, C, and F have unpaired electrons in their ground state configurations. Li has 1 unpaired electron in the 2s orbital, C has 2 unpaired electrons in the 2p orbitals, and F has 1 unpaired electron in the 2p orbitals. Ca, being in the s2 configuration in its outermost shell, has no unpaired electrons.
