Does the "electron from outside" that the oxygen receives, as indicated in the drawing, comes from the nitrogen atom? If so, then the N atom would be left with only 4 valence electrons instead of 5, thus being able to form another covalent bond with the extra oxygen, forming $\ce{NO3}$. Is this the correct line of thinking?

Jan 30, 2015 · The $\ce{NO3-}$ ion cannot be depicted using a single Lewis structure. However, its resonance structures are shown below: What this means is that the actual structure of the nitrate ion is somewhere in between the three structures shown below.

Feb 7, 2018 · $\begingroup$ Please, clarify: are you talking about $\ce{NO3-}$ anion or $\ce{NO3}$ neutral radical . $\endgroup$ – permeakra Commented Feb 7, 2018 at 12:22

Jun 4, 2015 · $\begingroup$ $\ce{BiO(NO3)}$ could probably be added to the list … to quote a fellow student in the ion lottery practical course. 'Found nitrate, didn’t dissolve; only one insoluble nitrate.' (Note: He meant that we wouldn’t have gotten any others.) $\endgroup$

Nov 18, 2018 · There are two ways to think of it. First: draw out the (major) contributing Lewis structures for both ions. Each iin has one pi bond, but it's shared between two linkages in $\ce{NO2^-}$ ion versus three linkages in the $\ce{NO3^-}$ ion. So the $\ce{NO3^-}$ ion has less pi bonding in each linkage making those bonds weaker overall.

May 16, 2023 · Increase the concentration of $\ce{NO3^-}$ in the solution to prevent formation of aqua complexes in accordance with Le Chatelier's Principle, as explained in the section Hydration Isomerism of $\ce{Fe(NO3)3}$ below.

Oct 26, 2017 · The brown ring formed in the confirmatory test for the nitrate ion is due to the complex called nitroso ferrous sulphate, or pentaaqua nitrosyl iron (II) sulfate with the formula $\ce{[Fe(H2O)5NO]SO4}$.

Dec 18, 2014 · The nitrate ion $\ce{NO3-}$ is what I like to call a Y-aromat since it has some similarity in the electronic structure. The bonding situation is very comparable to benzene. The resonance structures, however, look much more complicated.

Sep 11, 2012 · $$\ce{Ba(NO3)2(aq) + Na2CO3(aq)}$$ In the above reaction both the substances are in water, however water plays no role in the reaction. Why is it that although water is present in the reaction, it does not play a reactant role? To clarify, why isn't the above written as: $$\ce{Ba(NO3)2(aq) + Na2CO3(aq) + H2O}$$

Oct 22, 2018 · Because, unlike in other metal dissolution reactions, the $\ce{H+}$ of $\ce{HNO3}$ isn't reduced—the $\ce{NO3-}$ is. The following data and balanced reactions are taken from Wikipedia :
