Resonance and Geometrical Shape

Blog Post #2

In talking about resonance and geometrical structure, there were many factors that go into determining the shape. 

First off, there's bond polarity. When electrons are shared between two atoms, one atom may exert more of a force on the electron than the other one on the other atom. This pull is termed electronegativity. 

The unequal sharing of electrons within a bond leads to the formation of an electric dipole: a separation of positive and negative electric charges.
