Definition

An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions.

Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate. (See: Electrolytes)

Ions can be created using radiation such as x-rays. Ionizing radiation is often used for diagnostic or therapeutic procedures, since the ions that are produced can be used to scan for or treat some diseases.

How do hydroxyl ions and hydronium ions affect pH?

Hydroxyl ions (OH-) increase pH by combining with hydronium ions (H3O+) to form water molecules, reducing the concentration of hydronium ions. Hydronium ions (H3O+) decrease pH by increasing the concentration of hydrogen ions in the solution, making it more acidic.
