How many resonance forms can be written for the nitrate ion, (NO3^-)? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: The nitrate ion (NO3^-) has a central nitrogen atom bonded to three oxygen atoms. Step 2: The Lewis structure has one double bond and two single bonds, which can be placed between nitrogen and any of the three oxygens. Step 3: This results in three equivalent resonance structures.
