The Lewis symbols of some elements are shown here: Figure 1.2a The Lewis structures of aluminum, tin, nitrogen, chlorine and bromine. For simple diatomic molecules, combining the Lewis symbols of each element gives its Lewis structure. In order to draw a Lewis structure of acrolein (C 3 _3 3 H 4 _4 4 O), first we will have to count the total number of valence electrons, which is 22 (12 from C atoms, 4 from H atoms and 6 from O atoms). Two C atoms are bonded together with a double bond and one C atom has a double bond with O atom (carbonyl group - C=O). Step 3: Determine the Number of Bonds in the Molecule. Covalent bonds are formed when one electron from each atom forms an electron pair. Step 2 tells how many electrons are needed and Step 1 is how many electrons you have. Subtracting the number in Step 1 from the number in Step 2 gives you the number of electrons needed to complete the octets.
