Resonance

In this lesson, we learned about structure and resonance. In a nutshell, resonance is when a lewis structure can be drawn in multiple different ways for the same molecule. The shape change is displayed by a double headed arrow between the two structures.

We also checked out the shapes of molecules. When there is a structure with no non-bonding pairs, we have 5 different regions the structure can be. Depending on the number of bonds, it can be linear, trigonal planar, tetrahedral, trigonal bipyramid, and octahedral. If there are non-bonding pairs, the shape can be a asymmetrical form which will also be polar.
