Which statement is true about a polyatomic ion?

It forms metallic bonds with other ions.

It forms covalent bonds with other ions.

It is made of atoms that are covalently bonded together.

It has a charge that is distributed over part of the entire unit.

The correct option for above statement is

It is made of atoms that are covalently bonded together.

Explanation:

A substance particle, conjointly referred to as a molecular particle, may be a charged chemical species (ion) composed of 2 or a lot of atoms covalently secured or of a metal complicated that may be thought-about to be acting as one unit. The word poly - suggests that "many," in Greek, however even ions of 2 atoms are ordinarily noted as substance.

Among the given choices, which among them tells us the truth about the polyatomic ion. The polyatomic ions are charged molecules or formula units that are composed of many atoms. From the given choices, the answer would be letter C. It is made of atoms that are covalently bonded together. When we say covalently bonded, the atoms are shared among the atoms composing the formula unit.
