Chemical Ball and Spoke Model.  How do you explain when a rearrangement of the model is needed?

Chemistry teachers seem to use the ball and spoke model for describing a molecule of a chemical compound in order to teach the youngs its realistic comformation.

I think the model is too simplistic and rigid for young student who is pondering about its possible chemical transformation.

What does each spoke tell about its bond's meaning?

And when a chemical reaction occurs on the compound, then how does a teacher explain the general mechanism that changes the ball and spoke configuration?

This model gives students a fixed idea for chemistry.

Think a wild possibility of electron's behavior now being excavated by quantum mechanics!
