Problem
Rules for determining formal charge and Lewis Structures.
Step-by-step solution
The problem asks to identify correct statements about formal charge and Lewis structures. The correct statements are: Formal charge = valence electrons - associated electrons; Half of the atom's bonding electrons are associated with the atom; Small charges are preferred to large formal charges; Formal charges should be consistent with electronegativities; A Lewis Structure in which all formal charges are zero is preferred; All of the atom's non bonding electrons are associated with the atom; and Can be used to determine the most plausible Lewis Structure when more than one possibility exists for a compound.
