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.

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.
A binary compound is a chemical compound made up solely of 2 elements, for example P2O5, Na2O KCl. (The bonding is not relevant- it could be covalent or ionic.)A polyatomic ion is a cation or anion that contains more than one atom. Most contain 2 different elements. For examplepolyatomic anions:- [SO4]2-, [NO3]-polyatomic cation:-[ NH4]+ , [Hg2]2+

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-
They are a binary Compound (Only two Elements)
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.
chromium (III) bromide calcium chloride OR iron (III) oxide aluminum chloride
Sodium hydroxide (NaOH) is polyatomic (contain atoms of Na, O and H).
