Explanation:
In science, Hydronium is the regular name for the fluid cation [tex]H_3O^+[/tex], the kind of oxonium particle created by protonation of water.
It is the positive particle present when an Arrhenius acid is disintegrated in water, as Arrhenius acid atoms in arrangement surrender a proton (a positive hydrogen particle, [tex]H^+[/tex]) to the encompassing water particles [tex](H_2O)[/tex].
The chemical symbol of other ions given in the options is as follows:
- Hydrogen ions - [tex]H^+[/tex]
- Hydroxide ion - [tex]OH^-[/tex]
- Hydroxyl group - OH
