Potassium - Minerals Education Coalition

Potassium is a light, very soft, silvery-white metal. It is even more violently reactive with water than is sodium. It is so reactive with oxygen, that if exposed to air, it will tarnish to a grayish color in seconds. Potassium occurs with an abundant radioactive isotope, K40. Consequently, potassium metal is almost always faintly radioactive.
