O If there are any lone pairs, describe what type of orbital contains these electrons. Lewis structure C2H2Br2?. Three lone pairs on each chlorine atom. Noble gases have eight valence electrons (except Helium), and they are considered stable. For polyatomic anions, you must add electrons (equal to the negative charge) to the total number of valence electrons. It can only form two bonds. The symmetry causes the individual bond polarities to cancel out, resulting in a net non-polar molecule. Hybridization is one of the fundamental concepts used to explain the bond formation and was introduced by Pauling. Count the number of side atoms and let it be equal to B (arbitrary variable). 180 A covalent bond is formed when non-metal atoms share their valence electrons, which they do in order to achieve filled valence orbitals like their nearest noble gas neighbor.
