Polyatomic ions are charged molecules composed of multiple atoms bonded together. These ions behave as a single unit in chemical reactions despite containing several atoms. Understanding polyatomic ions is essential for students learning chemistry as they are common in many everyday compounds and play crucial roles in numerous chemical processes.
