Quizplus · Accepted Answer

The molecule COS has 1 carbon (C) atom, 1 oxygen (O) atom, and 1 sulfur (S) atom. Carbon has 4 valence electrons, oxygen has 6, and sulfur, being in the same group as oxygen, also has 6 valence electrons. Adding these together gives 4 (C) + 6 (O) + 6 (S) = 16 valence electrons.
