Phosphate is a triply charged polyatomic anion.
Na3 3+, PO4 3-. Na is actually +, so Na3 is 3+.
NH4 is called ammonium phosphate because it consists of the ammonium cation (NH4+) and the phosphate anion (PO4^3-). The compound is formed by the combination of these two ions, resulting in a salt known as ammonium phosphate.
Cesium is a cation, meaning it is a positively charged ion. It forms the Cs+ cation when it loses an electron.
Chloride is an anion. It carries a negative charge due to the gain of an electron.
The cation for sodium fluoride is Na+ (sodium ion).
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
The ionic compound for K3PO4 is potassium phosphate. It is formed by the combination of the potassium cation (K+) and the phosphate anion (PO4^3-).
The cation would be C6H5NH3+ and the anion would be C6H5NH-
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.
The cation of potassium cyanide is potassium (K+) and the anion is cyanide (CN-).

Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
According to Wikipedia, Ca(H2PO4)2: Calcium forms a divalent cation, and the polyatomic anion dihydrogen* phosphate has only a single negative valency.
Oxygen is neither a cation nor an anion. It is a neutral element.
Major Intracellular cation - K+ (Potassium) Major Extracellular cation - Na+ (Sodium) Major Intracellular anion - PO4+ (Phosphate) Major Extracellular anion - Cl- (Chloride)
CR is a cation.
