[114], There are thousands of uses of various potassium compounds.
Higher exposures may cause a build up of fluid in the lungs, this can cause death.
Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter).
Our editors will review what you’ve submitted and determine whether to revise the article. The chemistry of potassium is almost etirely that of the potassium ion, K+. Most potassium occurs in the Earth's crust as minerals, such as feldspars and clays. Both peroxides and superoxides may react explosively with metallic potassium. A synthetic vitamin K precursor called menadione (vitamin K3) is used as a vitamin supplement. Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. Now its your turn, "The more we share The more we have". Most chemical elements are represented symbolically by two letters, generally the first two in their name. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a key plant element.
If none of the data types are checked, there
After prolonged storage in air dangerous shock-sensitive peroxides can form on the metal and under the lid of the container, and can detonate upon opening. Chemical sym Name Origin of symbol Atomic No. K: Potassium: New Latin potassa, 'potash', iself from pot and ash (the symbol K is derived … To specify any number (including zero) of given [119] The ternary alloy of 12% Na, 47% K and 41% Cs has the lowest melting point of −78 °C of any metallic compound.
Number of Neutrons: 20. A very few elements have symbols which appear to have no relationship with their names. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. the search will be restricted to species which

A. McCleverty and T. J. Meyer (eds. element, use an asterisk (*) after the element symbol. Its applications include gold mining, electroplating, and electroforming of these metals; it is also used in organic synthesis to make nitriles.
The name for the element comes from the Latin word "kalium." [118], An alloy of sodium and potassium, NaK is a liquid used as a heat-transfer medium and a desiccant for producing dry and air-free solvents. Inhalation of dust or mists can irritate the eyes, nose, throat, lungs with sneezing, coughing and sore throat.
Together with nitrogen and phosphorous, potassium is one of the essential macrominerals for plant survival. will be no restrictions on the search.
the It was first isolated from potash, the ashes of plants, from which its name derives. Nice post.
When our kidneys are somehow malfunctioning an accumulation of potassium will consist. Melting Point: 63.65 °C (336.8 K, 146.57 °F) Boiling Point: 774.0 °C (1047.15 K, 1425.2 °F) Number of Protons/Electrons: 19. High water soluble levels of potassium cause damage to germinating seedlings, inhibits the uptake of other minerals and reduces the quality of the crop.
Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. These agents deprive the fire of oxygen and cool the potassium metal. National Institute of Standards and

Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. If correct case Please reply back as I'm planning to create my very own blog and would love to learn where you got this from or exactly what the theme is called.
These peroxides may react violently with organic compounds such as oils.
