| Formal Charge: |
Free online formal charge calculator – calculate the formal charge, enter the number of valence electrons, lone pair electrons and bonding electrons then click the calculate button.
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 charges?
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
