1 Potassium is made, along with several other elements including sulfur, and silicon, during explosive oxygen burning in supernovae. 2  All plants need potassium to survive; over 90% of all human use of potassium compounds is in the manufacture of plant fertilizers.
The chemical properties of potassium are similar to those of sodium, although the former is considerably more reactive. Potassium differs from sodium in a number of respects. Whereas sodium is essentially unreactive with graphite, potassium reacts to form a series of interlamellar compounds, the richest having the formula KC 8.
