Question

What are polyatomic ions? Give examples.​

Answer 1

Explanation:

answer:A polyatomic ion is also known as a molecular ion and it is a charged chemical species (ion) composed of two or more atoms covalently bonded. It can also be known as a metal complex that acts as a single unit. Example - SO2−4,CO2−3.

Answer 2

$\huge \red{answer}$

Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
