To calculate the formal charge of the nitrogen atom in NO, we can use the following formula:Formal charge = Valence electrons of the atom - Non-bonding electrons - 0.5 * Bonding electrons In the case of nitrogen, the number of valence electrons is 5. In the NO molecule, nitrogen forms two bonds with oxygen atoms: one single bond and one double bond. This means there are 2 from the single bond + 4 from the double bond = 6 bonding electrons.There are no non-bonding electrons on the nitrogen atom in NO, as all its valence electrons are involved in bonding.Now, we can calculate the formal charge:Formal charge = 5 valence electrons - 0 non-bonding electrons - 0.5 * 6 bonding electrons Formal charge = 5 - 0 - 3Formal charge = +2So, the formal charge of the nitrogen atom in the NO molecule is +2.
