Potassium is the 19th element. It is a soft silvery metal easily cut with a knife. Its density is less than water and it floats, however, it is so reactive that it spontaneously catches fire when it touches water, burning with a purple flame. It is one of the most highly reactive elements and is not found in a pure state. All cells use potassium and it is an essential element for life. Because it oxidizes upon contact with dry air, it must be stored under oil.
