🤓 Based on our data, we think this question is relevant for Professor Montano's class at UIC.
Draw the Lewis structures for three resonance forms of nitrate, NO 3-. Include electron lone pairs, and any formal charges.
We are being asked to identify the three resonance forms of NO3-.
First, we will have to draw the Lewis Structure of NO3-.
Step 1: Determine the central atom in this molecule.
• N → less electronegative atom than O → central atom
Step 2: Calculate the total number of valence electrons present.
Group Valence Electrons
N 5A 5 valence e‑
O 6A 6 valence e- x 3
= 23 valence e‑
-1 charge +1 e-
Total = 24 valence e-
Step 3: Draw the Lewis Structure for the molecule
