1 Remember that Hydrogen (H) atoms always go on the outside of a Lewis Structure. 2  Note that Hydrogen only needs two valence electrons to have a full outer shell. 3  In the Lewis structure for C 2 H 2 Br 2 there are a total of 20 valence electrons. Carbon is the least electonegative atom so it goes at the center of the C 2 H 2 Br 2 Lewis structure. 2  Remember that Hydrogen (H) atoms always go on the outside of a Lewis Structure. 3  Note that Hydrogen only needs two valence electrons to have a full outer shell.
