    An oxonium ion is a species containing an oxygen atom that has an octet of valence electrons, but bears a formal charge of +1. E.g.,


    Some oxonium ions are resonance stabilized, in which case not all resonance forms of the species fit the above definition, e.g.:


    Alternatively, the above species is a hybrid of an oxonium ion and a carbocation.
