We know the correct lewis structure of N2O is –
So, the central atom in lewis’s structure of N2O is Nitrogen (N). Let’s find the formal charge of it.
The formal charge can be calculated using the formula given below.
- Formal charge = [ valence electrons – nonbonding electrons- ½ (bonding electrons)]
For the Nitrogen (N) central atom
- Valence electrons of Nitrogen = 5
- Bonding electrons = 1 single bond(2 electrons) + 1 triple bond(6 electrons) = 8 electrons
- Non-bonding electrons = Zero lone pairs = 0 electrons
- Formal charge = 5 – 0 – 8/2 = 5 – 0 – 4 = +1
So, based on the analysis, the formal charge of the central atom in N2O is +1.
