A binary compound is a chemical compound composed of only two elements but a polaytomic compound is a compound made up of a polyatomic ion (two or more atoms chemically bonded together).
Na2Cr2O7 is an ionic compound with a polyatomic ion. The polyatomic ion present in this compound is the chromate ion (Cr2O7)^2-.
CaSO4 is a polyatomic ionic compound. It consists of a metal cation (Ca2+) and a polyatomic anion (SO42-) that are attracted to each other through ionic bonds.
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
The charge of the polyatomic ion is occasionally included in the chemical formula for a compound containing it. This charge is never used in a binary ionic compound because binary compounds involve only two elements with differing charges, while polyatomic ions already contain multiple elements and an overall charge.
Phosphorus pentachloride is a covalent compound.

A binary compound is composed of two different elements, while a polyatomic ion is a charged group of two or more atoms bonded together. Binary compounds do not form ions by themselves, while polyatomic ions have a net charge and act as a single unit in chemical reactions.

A non-binary compound is a chemical compound composed of two different elements. This means that it does not contain more than two types of atoms in a single molecule. Examples include sodium chloride (table salt - NaCl) and water (H2O).
Silver nitrate is AgNO3 so it is not a binary compound as it contains three elemnts. The term binary ionic is unusual - chemists normally say a binary compound, binary ionic may be taken to mean just two sorts of ions in which case it would be classified as a binary ionic as ther are two ions Ag+ and NO3-
No, dinitrogen teroxide (N2O4) is a molecular compound, not a binary ionic compound. Binary ionic compounds are formed between a metal and a nonmetal through the transfer of electrons, while molecular compounds result from the sharing of electrons between nonmetals.
They are a binary Compound (Only two Elements)
chromium (III) bromide calcium chloride OR iron (III) oxide aluminum chloride
Sodium hydroxide (NaOH) is polyatomic (contain atoms of Na, O and H).
