Sketch, on paper, the Lewis structure of CO, remembering to: Step 1: Arrange the atoms Step 2: Count the number of valence electrons. Step 3: Allocate two electrons between each pair of atoms which are assumed to be covalently bound. Step 4: Use the remaining valence electrons to form lone pairs, and/or double and triple bonds.
