Lewis structure
Draw the Lewis structure of chlorine monoxide. Start by drawing the overall structure of the molecule: Count the total valence electrons of the chlorine (n_Cl, val = 7) and oxygen (n_O, val = 6) atoms: 2 n_Cl, val + n_O, val = 20 Calculate the number of electrons needed to completely fill the valence shells for chlorine (n_Cl, full = 8) and oxygen (n_O, full = 8): 2 n_Cl, full + n_O, full = 24 Subtracting these two numbers shows that 24 - 20 = 4 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 2 bonds and hence 4 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 20 - 4 = 16 electrons left to draw: Answer: | |
