What are lewis structures?
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line. The octet rule and formal charges must be satisfied if the "optimal" electron configuration is to be achieved.
The formal charges are necessary for any Lewis structure. The goal is to have as minimal formal charges as possible, or formal charges of 0 for the majority of the atoms in a structure.
Formal charges should be on more electronegative atoms since they are more electronegatively inclined, and vice versa.
