Potassium, the second lightest metal, was discovered by Sir Humphry Davy in 1807. It reacts violently with water and can even catch fire spontaneously in water. It can be found bound to other elements in seawater and minerals, and is needed for plant growth. Potassium is commonly u...

The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about potassium -- an "evil" element, but one that's crucial to life. In this video, see some violent explosions and the gentle creation of a pota
Therefore, potassium (K) and sodium (Na) are utilized due to their closest position to lithium in the same group on the periodic table, hence have similar physical and chemical characteristics. The chemistry of M-S batteries is fairly same; it can be utilized via liquid electrolytes containing...
What do you think of when you look at element number 19 on the periodic table? As a chemist, I suppose my head should be filled with images of chemically related things involving potassium, such as zeolite structures being charge-balanced by K~+, but instead I think of what has to be ...
Another major advantage is that it is able to determine almost all the elements in the periodic table – including potassium –simultaneously at very low concentrations. XRF is based on bombarding a small area of the sample with x-ray photons, which are sufficiently energetic to cause ionization...
Relative atomic mass (Ar): 39.0983 (1) Standard state: solid at 298 K Appearance: silvery white Classification: Metallic Group in periodic table: 1 Group name: Alkali metal Period in periodic table: 4 Block in periodic table: s Shell structure: 2.8.8.1 CAS Registry: 7440-09-7Potassium...
Potassium is a chemical element with the symbol ‘K’ on the periodic table. It is one of the most abundant minerals in the body and is primarily found inside cells. Potassium functions as an electrolyte, meaning it carries a small electrical charge that facilitates various physiological processes...
Potassium is a soft, silver-white metal. Physically and chemically it resembles the otheralkali metalsin Group 1 of theperiodic table. It is extremely reactive, more so than sodium. It combines so readily with oxygen that it is usually stored submerged in kerosene or some other hydrocarbon, ou...
