Give one example of a polyatomic element and polyatomic ion?

Ozone (O₃) is an example of a polyatomic element, and Sulfate (SO₄²⁻) is an example of a polyatomic ion. Polyatomic elements are made of more than two atoms of the same element. Polyatomic ions are charged groups of different atoms bonded together that act as a single unit.

• Ozone (O₃): Contains three oxygen atoms bonded together. It is a natural form of oxygen found in the Earth's atmosphere.
• Sulfate Ion (SO₄²⁻): Contains one sulfur atom and four oxygen atoms. It carries a negative charge and is found in many salts.
