Nitrate ion template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
NO₃⁻: N⁺ with one N=O and two N–O⁻ bonds; an O⁻ lone pair forms N=O as the N=O π bond moves to another O, giving three equivalent forms.
What the template shows
- Three equivalent contributors for NO₃⁻, each with N⁺ and two O⁻
- Resonance contributors
- Three equivalent forms
- All three N–O bonds are equal (about 125 pm), bond order 1⅓; the ion is planar.
- Nitrogen has an octet and a formal charge of +1 in every form; it cannot form a second N=O (that would need ten electrons on N).
- Total charge −1 = (+1 on N) + (−1 on each of two O).
- Contributors are not in equilibrium: the real species is one hybrid of them · every part of this figure is editable
Drawn with 12 atoms, 6 arrows, 2 shapes – every one editable in MolDraw.

Frequently asked questions
Is the Nitrate ion template free?
You can preview the Nitrate ion template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates.
Can I edit the Nitrate ion template?
Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.
Is the chemistry checked?
Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.
How are resonance structures shown?
Each contributor is drawn separately, joined by double-headed resonance arrows, with curly arrows showing how the electrons move from one contributor to the next.
