39K Information

Potassium is a soft silvery metallic element belonging to group 1 of the periodic table (alkali metals). It occurs naturally in seawater and in many minerals. Highly reactive chemically, this element resembles sodium in its behavior and compounds. Potassium was discovered by Sir Humphry Davy in 1807. Potassium has 26 isotopes. 3 of them are naturally occurring, 2 of which are stable.

Potassium is used as potash in making glass & soap. Also as saltpeter, potassium nitrate (KNO3) is used to make explosives and to color fireworks in mauve. Formerly potassium was called kalium (K). Potassium is vital to function of nerve and muscle tissues.
