K 19 Potassium
Potassium metal is an abundant element, which in its pure form is a silvery white, light metal and it is very reactive. Potassium metal reacts very strongly with water, producing hydrogen gas and flames. When dealing with potassium metal, painstaking precaution is inevitable. In compounds, potassium is essential to animals and plants, several natural minerals contain it. Potassium has a natural and radioactive isotope, called 40K (potassium 40), it is a beta emitter, and it has a half life of 1.25 billion years. It is responsible for the largest part of the normal radioactive exposure, and traces were discovered in bananas!
