## Formal Charge Formula

To calculate the formal charge, you can use the following formula:

**FC = VE – (LPE + 0.5 BE)**

- FC = Formal charge of the atom
- VE = Number of valence electrons
- LPE = Number of lone pair electrons
- BE = Number of bonding electrons

## How to calculate formal charge?

Here’s a step-by-step guide

- First, Determine the number of valence electrons
- Next, Count the number of lone pair electrons
- Next, Count the number of bonding electrons
- Finally, Put all values into the above formula of formal charge
