Molecular Geometry and Bonding Theories We saw in Chapter 8 that Lewis structures help us understand the compositions of molecules and their covalent bonds. This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push away from) each other in three dimensional space and this gives the molecules their shape. It's a triple bond so it will not be able to move at all. As per the octet rule, still each atom needs two more electrons to complete its outermost shell. Both the bonds help to identify the type of hybridization by either forming head-to-head overlap or when 2p orbitals overlap.
