What is the formal charge of NH3
The formal charge of NH3 (ammonia) can be calculated using the formula:
Formal charge = Valence electrons - (Number of lone pair electrons + 1/2 * Number of bonding electrons)
For ammonia (NH3):
Valence electrons for N = 5
Valence electrons for H = 1
Total valence electrons = 5 (N) + 3(1) = 8
Number of lone pair electrons on N = 1
Number of bonding electrons (from N-H bonds) = 3
Formal charge = 5 - (1 + 1/2 * 3) = 0
Therefore, the formal charge of ammonia (NH3) is 0.
