How to Calculate Formal Charge?


The charge assigned to an atom in a molecule is formal charge. This is calculated by the equation FC=V-N-2. V=valence electrons, N=non-bonding electrons, B= number is electrons shared in covalent bonds.

Formal charge is defined as the apparent charge of an atom present in a given compound. It is calculated by subtracting the number of valence electrons present in the neutral atom from the number of electrons in lone pairs + 1/2 of the number of electrons in bonds. You can obtain the number of valence electrons from the periodic table.
