Formal Charges

We use our knowledge of valance electrons to determine what he formal charge of the molecule will be. 

Formal and Net Charge

Easiest formal charge formula you will find anywhere on the internet: 

The Net Charge is the sum of all the formal charges on a molecule. 

Problem: Calculate the net charge of the molecule

3m

Problem: Calculate the total charge of the molecule

2m

Hell yeah! That’s literally all there is to know. Don’t let any professors complicate it more for you.
