Cations form when an atom loses electrons, resulting in a positive charge. This commonly happens with metals, like sodium (( Na )), which loses one electron to form ( Na^+ ). Anions form when atoms gain electrons, becoming negatively charged. Nonmetals, like chlorine (( Cl )), gain an electron to form ( Cl^- ). These oppositely charged ions attract each other, forming ionic compounds like NaCl (table salt).<\/p>\n\n\n\n<p>Polyatomic ions are unique because they consist of multiple atoms bonded together, yet they carry an overall charge. Unlike monatomic ions (single atoms with a charge), polyatomic ions like sulfate (( SO_4^{2-} )) or ammonium (( NH_4^+ )) act as a unit in chemical reactions. The atoms in a polyatomic ion share electrons covalently, but as a whole, the group has lost or gained electrons, making it an ion.<\/p>\n\n\n\n<p>The key difference among them is that cations and anions are usually single atoms with a charge, while polyatomic ions are groups of atoms with a charge. However, they all share the property of having an electrical charge, which makes them important in forming compounds and conducting electricity in solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Compare cations, anions, and polyatomic ions.
