Polyatomic ions ending in -ate in common form contain oxygen.
Anions and cations are ions of a single atom of a single element (i.e. Lithium+1, Fluorine-1, etc.). Polyatomic ions are charged particles composed of multiple atoms of different elements (i.e. Nitrate (NO3)-1, Ammonium (NH4)+1, etc.).
A polyatomic molecule is a molecule that contains more than two atoms chemically bonded together. The valence electron structure of all atoms in a polyatomic molecule contributes to the molecule's overall chemical behavior and properties, as it determines how the atoms interact with each other to form bonds and stabilize the molecule.
Germanium can form ions, although it is more common for germanium to share electrons in covalent bonds rather than donate or receive electrons to form ions. In certain chemical reactions, germanium can lose or gain electrons to form Ge2+ or Ge4+ ions, but this is less common compared to other elements.
All nickel atoms and ions share the same atomic number, which is 28, meaning they all have 28 protons in their nuclei. This characteristic defines them as nickel, regardless of whether they are neutral atoms or charged ions. Additionally, nickel atoms and ions have similar chemical properties due to their configuration of electrons, particularly in their outer shells, which influences their reactivity and bonding behavior.
The polyatomic ion we often see in a base is the hydroxide ion, which has OH- as its chemical formula. Some examples of bases are lithium hydroxide, sodium hydroxide, potassium hydroxide and calcium hydroxide. They are written LiOH, NaOH, KOH and Ca(OH)2, respectively.
For example no3 or co3 are all polyatomic ions
All ions have an electrical charge.
Except chloride, all others are polyatomic ions.
This isn't a rule.
No. Not only is it not true, but it it were, there would be no polyatomic ions!

Polyatomic ions.
Carbon monoxide is not a polyatomic ion. In fact, it isn't an ion at all! Carbon monoxide does consist of two different elements (and is therefore a bimolecular compound), but it is a neutral species.
Atoms can covalently bond together to produce a polyatomic ion, which can form a salt with another ion of opposite charge. Carbonate, phosphate, sulfate, nitrate, acetate, and other alkanoate salts all illustrate this phenomenon.
Examples of compounds include sulfate (SO4^2-), nitrate (NO3^-), phosphate (PO4^3-), carbonate (CO3^2-), and chromate (CrO4^2-), which all contain oxygen in their polyatomic ions.
Assuming that questioner intended to complete the question with "carbonate, or nitrate" instead of the nonexistent "carbonatenitrate": Carbonate and nitrate ions are both polyatomic; lithium and calcium ions are both monatomic.
All acids have hydronic ions.
