Formal Charge
Interpretation:
Detailed Calculation
Formula Used:
Formal Charge = V – NB – B/2
Where:
V = Number of valence electrons in the free atom
NB = Number of non-bonding electrons
B = Number of bonding electrons (Number of bonds × 2)
V = Number of valence electrons in the free atom
NB = Number of non-bonding electrons
B = Number of bonding electrons (Number of bonds × 2)

About Formal Charge
What is Formal Charge?
Formal charge is a concept used in chemistry to determine the distribution of electrons in a molecule. It helps predict the most stable Lewis structure for a molecule.
Formula
Formal Charge = V – NB – B/2
Where V is valence electrons, NB is non-bonding electrons, and B is bonding electrons.
Interpretation
- Zero formal charge is generally most stable
- Negative formal charge indicates excess electrons
- Positive formal charge indicates electron deficiency
