FreeScienceLectures | Potassium Reacts with Water @FreeScienceLectures | Uploaded 17 years ago | Updated 1 hour ago

Potassium is a chemical element. It has the symbol K (Latin: kalium) and atomic number 19.
The name "potassium" comes from the word "potash", as potassium was first isolated from potash.
Potassium is a soft silvery-white metallic alkali metal that occurs naturally bound to other elements in seawater and many minerals. It oxidizes rapidly in air and is very reactive, especially towards water. In many respects, potassium and sodium are chemically similar, although organisms in general, and animal cells in particular, treat them very differently.
In this video a piece of potassium is thrown into water which causes it to oxidize very very quickly thus releasing lots of energy which can be seen in form of sparks and fire.
