Potassium K

Abstract

Potassium is too reactive an element ever to be found as native metal, but is common in the combined state. It is an essential constituent of all plant life but in quantities far too small to be a source for the metal. The compounds of potassium are all water soluble, yet seawater contains very little of this metal. This would appear to be caused by the greater affinity of soil and plant life for potassium than sodium and magnesium, both of which can be recovered from seawater in economic quantities.
