An intermediate of this type is formed on a carbon chain during E1 and SN1 reactions. That intermediate is carbenium and assumes an sp2 hybridized state. A molecular example of this chemical species is arenium, which is stabilized by pi bond delocalization. Coordination complexes occur when ligands bind to these entities. Metals in aqueous solutions usually form these chemical species, which tend to have smaller atomic radii than their neutral or oppositely-charged counterparts because of these species' relative lack of electrons. A hydrogen form of this type of species is a bare proton. For 10 points, name these positively charged chemical species, contrasted with anions.
