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).
Polyatomic ionic.
Non-binary or polyatomic compounds are covalently bonded atoms with a net charge.
They are a binary Compound (Only two Elements)
Ionic with a polyatomic ion.
It is true of binary ionic compounds but not necessarily of compounds containing polyatomic ions.

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+

No. Not all binary compounds are ionic and not all ionic compounds are binary. An ionic compound is a compound formed by the exchange rather than the sharing of electrons. A binary compound is any compound of exactly 2 elements. Examples: Sodium chloride (NaCl, compound sodium and chlorine) is both binary and ionic. Potassium hydroxide (KOH, compound of potassium, hydrogen, and oxygen) is ionic but not binary. Water (H2O, compound of hydrogen and oxygen) is binary, but covalent, not ionic.
Type one binary compounds have a cation (+ charge) that has only 1 possible oxidation state, for example sodium (Na^1+). In type 2 binary compounds, the cation can have more than one oxidation state, for example iron which can be 2+ or 3+.
Iron (III) bromine, or FeBr3 is a binary ionic compound. Its ions are the metal Fe and the non-metal Br (the number of bromines per molecule doesn't influence the answer). A polyatomic ion is one which has one or more atoms of two or more elements, such as carbonate (CO3), hydroxide (OH), or nitrite (NO2), just to name a few.
Sodium hydroxide (NaOH) is polyatomic (contain atoms of Na, O and H).
No binary compound between beryllium and sodium.
Sodium sulfide has the formula Na2S it is the binary compound of the elements sodium and sulfur. It is very basic (alkaline). Sodium fluoride has the formula NaF. It is the binary compound of the elements sodium and fluorine. It is only mildly basic.
