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.

What is the formula for the tin ions?
The formula for tin ions depends on their charge. Tin can exist as Sn2+ ions (called stannous ions) or Sn4+ ions (called stannic ions). The formula for stannous ions is Sn2+ and for stannic ions is Sn4+.

What is the individual ions for iron iii and sulfate?
The individual ions for iron (III) are Fe3+ ions. The individual ions for sulfate are SO4^2- ions.
Ions that are made of more than one atom are examples of what?
Ions made up of more than one atom are called polyatomic ions.
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.
What is found in a glass of water?
If the water is pure, it will contain H3O+ ions and OH- ions. They are hydronium ions and hydroxyl ions.
What is the name of the following ions?
Cations -- which are positive ions -- and anions, which are negative ions.

What's the direction sodium ions are pumped?
Sodium ions and potassium ions are pumped in opposite directions. Sodium ions are pumped out of the cell and potassium ions are pumped into the cell.
