An oxonium cation is a polyatomic cation with a charge of +1 with a central oxygen bonded to three groups or elements Examples:- H3O+ is the oxonium cation, (C2H5)3O+ is the triethyloxonium cation.
metals
Alkaline-earth elements form cations.
The compound AgCrO4 is named silver chromate. It consists of silver (Ag) as the cation, and chromate (CrO4) as the anion. The name is derived from the combination of the names of the two elements involved.
Strontium can be a neutral atom or a cation.
The cation is hydrogen (+) - H(+).

metals
The cycloheptatrienyl cation is a stable aromatic compound with a planar structure. It is highly reactive due to its electron-deficient nature, making it prone to nucleophilic attack and electrophilic substitution reactions.
according to difference in electronegativity of elements(+ cation , - anion) , activity of elements
why the first elements and eighth elements shows similar properties
cation
Alkaline-earth elements form cations.
Divalent cation: Ca2+ Trivalent anion: (PO4)3-
Gold is cation since when its electrons are removed from its valence shell, it becomes positive. It is easier for gold to be stripped of its electrons to follow the octet rule therefore it is a cation.
