It is in a Ionic bond.
Polyatomic
ionic bond between aluminium cation and phosphate anion
The atoms in a polyatomic ion are held together with covalent bonds, but polyatomic ions combine with ions of opposite charge to form ionic compounds.
CO3(2-) and PO4(3-) Carbonate and phosphate. Both polyatomic compounds that have their constituent atoms bonded covalently. The can ionicly bond to metals. For instances, MgCO3 ( magnesium carbonate )
Ionic bonds and also covalent bonds

The bond between the copper and carbonate is ionic since the copper is positive (cation) and the carbonate is negative (anion) therefore the two opposing charges are attracted to each other. Carbonate is a polyatomic ion though therefore having a covalent bond. Therefore there is a covalent and ionic bond within Copper Carbonate.
It is formed from a metal (Li) and a polyatomic anion (Cr2O7^2-), so it is IONIC.
It is ionic
No, it is not a covalent bond. It is an Ionic bond.

There is ionic and covalent bonds: Ionic - SO4 is a polyatomic ion with a charge of 2-, so the molecule can be represented as H22+ SO42- Covalent - There are also covalent bonds between the S-O atoms
It is ionic, because any bond between a hydrogen atom and a polyatomic ion (Hydrogen + polyatomic ion = acid) is always ionic. H+ plus Cl-: hydrogen is a positive ion, chlorine is a negative ion, they attract, HCl is formed, which is hydrochloric acid.
