If an element with a high electron affinity (like oxygen) is part of a polyatomis molecule. one or more of the missing valence e' can sometimes be filled by a nearby extra e' instead of sharing elctrons with other atoms:)
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.
They are molecules.No they are generally called molecules. However there are polyatomic ions that are charged molecules, such as SO42-
Na2O is ionic and consists of Na+ and O2- ions.
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.
Covalent bonds typically form between diatomic atoms and in polyatomic ions. In covalent bonds, atoms share electrons to achieve a stable electron configuration. This sharing allows atoms to fill their outer electron shells and become more stable.
Covalent bonding is predominantly within polyatomic ions.

Ionic bonds. These bonds are formed through the transfer of electrons between atoms, resulting in the formation of charged particles known as ions within the polyatomic ion. The attraction between the positively and negatively charged ions holds the polyatomic ion together.

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.
Ions made up of more than one atom are called polyatomic ions.
Ions are charged particles formed by gaining or losing electrons, while polyatomic ions are charged groups of atoms that remain together and carry a net charge. Polyatomic ions contain multiple atoms bonded together, whereas ions can be a single atom or a group of atoms.
