We use our knowledge of valance electrons to determine what he formal charge of the molecule will be.
Concept #1: Calculating 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.
Calculate the formal charge of the following molecule:
Concept #2: Calculate the formal charges of ALL atoms.
Practice: Calculate the net charge of the molecule
Practice: Calculate the total charge of the molecule
Hell yeah! That’s literally all there is to know. Don’t let any professors complicate it more for you.
