Potassium is a soft, reactive metal that is essential for cellular function and electrolyte balance in organisms.
Properties of Potassium | It reacts vigorously with water, has low density and forms soluble salts such as potassium chloride and nitrate.
Uses of Potassium | Potassium compounds are mined for fertilizers, used in chemical synthesis and play key roles in physiology and agriculture.
Isotopes of Potassium | Stable K 39, K 40 radioactive and K 41 isotopes exist; K 40 contributes to natural radioactivity and metallic potassium is highly reactive and stored under oil.
