------------------------------------------------ Determine the overall formal charge on each atom in the compound NO₃⁻, given that the formal charges are not listed on the resonance structures.

A. Nitrogen

B. Oxygen

Answer :

Final answer:

The overall formal charge on nitrogen in NO₃⁻ is +1 and the overall formal charge on each oxygen atom is -1.

Explanation:

The overall formal charge on each atom in the compound NO₃⁻ can be determined by considering the resonance structures of the compound. Nitrogen (N) is bonded to three oxygen (O) atoms in NO₃⁻.

One of the resonance structures of NO₃⁻ has a double bond between one of the oxygen atoms and the nitrogen atom. In this structure, the nitrogen atom has a formal charge of +1 and each oxygen atom has a formal charge of -1. The other resonance structures of NO₃⁻ also have the same formal charges for the atoms.

So, the overall formal charge on nitrogen in NO₃⁻ is +1 and the overall formal charge on each oxygen atom is -1.
