Phosphate (PO43-) is a polyatomic anion. The way to tell this is to look at the charge - an anion has a negative charge and a cation has a positive charge.
The ion PO43- belongs to the category of polyatomic ions, specifically the phosphate ion. It is a negatively charged ion composed of one phosphorus atom and four oxygen atoms.
The two components of a salt are a positively charged ion (cation) and a negatively charged ion (anion). The cation is usually a metal or a positively charged polyatomic ion, while the anion is usually a nonmetal or a negatively charged polyatomic ion.
An example of an ionic compound with a polyatomic cation and anion, where the atoms in the anion are all from the same group, is ammonium phosphate (NH4)3PO4. Here, the cation is the ammonium ion (NH4+), a polyatomic cation, and the anion is the phosphate ion (PO4^3−), which contains phosphorus and oxygen, both belonging to Group 15 and Group 16 of the periodic table, respectively. However, the phosphate itself does not have all its atoms from the same group; for a strict interpretation, consider a compound like ammonium sulfate ((NH4)2SO4), where the sulfate ion (SO4^2−) has sulfur from Group 16 and oxygen from Group 16 as well.
anion
Anion is a negative ion (Cl-) and cation is a positive ion (Na+).
polyatomic anion
Hydronium is a polyatomic cation.
An example of this type of compound is ammonium sulfate (NH4)2SO4, where the polyatomic cation is ammonium (NH4+) and the polyatomic anion is sulfate (SO4^2-). In this case, the atoms in the sulfate anion are all from the same group in the periodic table (Group 16 or the oxygen family).

The ion PO43- belongs to the category of polyatomic ions, specifically the phosphate ion. It is a negatively charged ion composed of one phosphorus atom and four oxygen atoms.
Chromate is an divalent anion with formula CrO4-2
Well, a polyatomic may contain a cation in it. A cation is a positively charged ion. They are usually metals. A good way to remember is: "cats" have "paws" because they are "pawsitive". Cheesy, right? Anyways, an example of a polyatomic that contains a cation is NH4+. You know that this polyatomic has a cation by the +1 superscript. This + sign signifies a positive ion, which is called a cation!
The chemical name for an ionic compound with a polyatomic cation and polyatomic anion would typically be named using the names of the individual ions. The cation would be named first followed by the anion, with the ending of the anion typically changed to "-ide," similar to naming binary ionic compounds.
A compound consisting of a metal cation and a non-metal or polyatomic anion.
Phosphate is a triply charged polyatomic anion.
The principal ions in coconuts water are: cations as K+, Na+ and Fe2+, anions as Cl- and PO43-.
The two components of a salt are a positively charged ion (cation) and a negatively charged ion (anion). The cation is usually a metal or a positively charged polyatomic ion, while the anion is usually a nonmetal or a negatively charged polyatomic ion.
