Potassium (K ) by %

**Potassium (K) Element Properties**
Atomic Mass	39.0983
Atomic Number	19
Name Origins	English, potash; Latin kalium.
Year Discovered	1807
Discovery Credits	Sir Humphry Davy at London, UK.
Remarks	Soft white metal, silvery when cut but reacts rapidly with oxygen and vigorously with water. Metal obtained from NaCl + KCl at 1100 K. Used in fertilizers, chemicals, and glass. Diagnostic tests: In solution, a potassium will give a violet flame test color. This flame test will be contaminated with the colors of the other alkaline elements which are present in the sample. The test is best observed through a blue filter or Glass blowers Didymium Safety Glasses to suppress the yellow sodium flame.
