An ion is an atom or molecule that has an electric charge because it has gained or lost electrons. If it loses electrons, it becomes a positive ion. If it gains electrons, it becomes a negative ion.
People usually talk about ions in science, especially in chemistry, biology, and technology. You may hear about ions in batteries, salt water, air purifiers, or even in the human body, where they help carry signals and support normal body functions.
Meaning & Usage
The word ion is used when something has a charge and can interact with other charged particles. In simple terms, ions are tiny particles that help explain how many natural and scientific processes work.
Examples
For example, sodium and chloride are ions in table salt. In a battery, ions move to help produce electricity. In the body, ions like sodium, potassium, and calcium help nerves and muscles work properly.
