Question

Which of the following statement is correct for NO3- ion? (A) Sum of all formal charges = +1 (B) Formal charge on one of the oxygen atom = -2 (C) Formal charge on nitrogen atom = +1 (D) Average formal charge on oxygen atom =-(1/3)

Here formal charge on N-atoms is +1 and average formal charge on oxygen atom is -(2/3) <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-wkdqrgmb8mnv.png" />

Q. Which of the following statement is correct for $N O_{3}^{-}$ ion?

Sum of all formal charges = +1

Formal charge on one of the oxygen atom = -2

Formal charge on nitrogen atom = +1

Average formal charge on oxygen atom $= - \frac{1}{3}$

Here formal charge on N-atoms is +1 and average formal charge on oxygen atom is $- \frac{2}{3}$
