I’m reviewing the chemistry concept of formal charge. There are three simple rules:
Have as few formal charges on the molecule as possible.
Separate like charges.
Put negative formal charges on electronegative atoms.
Lewis structures are unnecessary to practice these rules. We can picture pairs of graphs. Red vertices represent electronegative atoms. The labels representing formal charge.
I decide which has a more favorable formal charge distribution, according to the rules.
This game took me longer to describe than to invent and play. Score one for mental practice.
