Properties of potassium include:

  • Good conductor of electricity
  • Reacts with water to form potassium hydroxide
  • Has a low melting and boiling point
  • Density of 0.86 g/cm3
  • Highly reactive and can ignite spontaneously in air

Potassium is commonly found in many minerals and rocks and is an important component of many salts, including potassium chloride and potassium nitrate. It is also found in seawater, where it is the seventh most abundant element. Potassium plays an important role in the functioning of cells, the regulation of fluid balance in the body, and the transmission of nerve impulses.
