Potassium

Potassium is a soft, silvery coloured metal, which like other members of the alkali group of metals, is extremely reactive. As with other members of the group, it can be prepared by electrolysis of the fused halide. The main source being potassium chloride. It does not occur naturally. Potassium has limited use as the pure metal, although it can be
