A polyatomic ion is charged and will form ionic bonds; for example, the sulfate ion SO42- forms many compounds, such as sodium sulfate. The bonds holding polyatomic ions together are covalent.
K2SO4 is an ionic compound. It is formed by the ionic bonding between potassium ions (K+) and sulfate ions (SO4^2-).
Na2O is ionic and consists of Na+ and O2- ions.
It is possible for a compound to possess both ionic and covalent bonding. a. If one of the ions is polyatomic then there will be covalent bonding within it. b. When a polyatomic ion combines with another ion, then there is an ionic bond
Polyatomic ions can have both ionic and covalent bonds. Ionic bonds are formed between the positively and negatively charged ions within the polyatomic ion, while covalent bonds are formed by sharing electrons between the atoms within the polyatomic ion.
Polyatomic ion ammonium is the exception. When some non-metals contain polyatomic ion ammonium and mix with a metal/metalliod and some times even non-metals the reaction is ionic.

Covalent bonding is predominantly within polyatomic ions.

Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.

K2SO4 is an ionic compound composed of potassium ions (K+) and sulfate ions (SO4^2-).
Compounds with both ionic and covalent bonds contain polyatomic ions. These ions consist of more than one atom covalently bonded together and carry a net charge, making them act as single units in ionic compounds.
If the bonding is covalent, then they are just called atoms but when in ionic bonding they are called ions.
