Question

a lewis structure for the nitrate ion (no₃⁻) is shown on the left below. draw another equivalent resonance structure of no₃⁻.

Explanation:

Resonance structures involve the delocalization of electrons. In the nitrate ion (\(NO_3^-\)), the double - bond can be moved to another oxygen atom.

Answer:

The equivalent resonance structure can be drawn by moving the double bond from one oxygen to another. For example, if in the given structure the double bond is with the bottom - left oxygen, in the new resonance structure, the double bond can be with the top - or bottom - right oxygen. The general form would have \(N\) in the center, one \(O\) with a double bond (different from the original structure) and two \(O\) with single bonds and extra electron pairs (to account for the negative charge).
