- linear electron domain - there is only one molecular geometry, this one, for a molecule having a linear electron domain geometry. Trigonal planar family molecular geometry - trigonal planar - all bonding pairs (AB3) bent - one nonbonding pair (AB2E)
- Describe the role of unshared electron pairs in predicting molecular geometry. they influence the shape of the molecule. if there are unshared electron pairs on the central atom of a linear molecule. those electrons can push the atoms farther away and form a bent structure. they take up space and present a force.

A chemical bond formation is attributed to the tendency of a system to attain stability. It was observed that the inertness of noble gases was because of their fully filled outermost orbitals. Hence, it was postulated that the elements having incomplete outermost shells are unstable (reactive).
