### Contribution in Formal Charge

In the textbook, where it discusses the Correcting of the Covalent Model and the formal charge, they often mention "contribution" but I am not entirely sure what they are referring to in that. For example, in the section Correcting the Covalent Model the book states that because Chlorine has a greater attraction for the (e-) than Hydrogen does in the compound HCl, then the structure with the negative charge on the Chlorine makes a bigger "contribution" than if the negative charge was on the Hydrogen.

### Re: Contribution in Formal Charge

A lewis structure that makes a greater "contribution" to the actual structure is a better representation of the actual structure.

This is referring to modeling a chemical as a blend or compilation of possible Lewis structures. The most stable or more likely structure makes a greater "contribution" to the blend (like with resonance structures).
