How is an anion stabilized?

I think that the electronegative anion induces the negative charge and stabilizes it. Also, resonance structures stabilize too

I would like to add that in oxoacids, when stabilization occurs, the negative charge around the molecule is delocalized which weakens the attraction between O-H. This creates a stronger acid because the H+ is more likely to break off.

The electronegative atoms that adjacent to the charged anion will stabilize it I believe.

In solution, an anion can be stabilized by ion-dipole interactions with electropositive hydrogens for example(-15 kJ/mol). This would reduce the energy of the anion, stabilizing it.

I believe an anion is stabilized when regions of electron density around the atom are delocalized.
