Occurs only in compounds. Atomic Mass 39,0983 Learn more about the atomic mass. Since all alkali metals have a single electron in their outermost shell, K too has a single electron in its peripheral orbital. Popular Questions. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). Values are given for typical oxidation number and coordination. Melting Point: 336.53 K (63.38°C or 146.08°F) Boiling Point: 1032 K (759°C or 1398°F) Density: 0.89 grams per cubic centimeter. Our support group for Potassium has 36 questions and 81 members. [115][116], Another example is potassium cobaltinitrite, K3[Co(NO2)6], which is used as artist's pigment under the name of Aureolin or Cobalt Yellow. Potassium is element number 19. Eighth most abundant element in the earth's crust (20,900 ppm). The sum of the oxidation states within a compound or ion must equal the overall charge. This, then, is immediately put into large copper Pots, and is there boiled for the space of three days, by which means they procure the Salt they call Potas, (which signifies Pot-Ashes) on account of its being thus made in Pots. The arrangements of electrons above the last (closed shell) noble gas. Uncombined elements have an oxidation state of 0. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. Phase at Room Temperature: Solid. Naiturally occurrin potassium is componed o three isotopes, o which 40 K is radioactive. The images may not be posted on any website, shared in any disc library, image storage mechanism, network system or similar arrangement. Contents .

Values are given for typical oxidation number and coordination. E) have the same mass number. Potassium metal can react violently with water producing potassium hydroxide (KOH) and hydrogen gas. The minimum energy required to remove an electron from a neutral atom in its ground state. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. [110][111], Potassium nitrate (KNO3) or saltpeter is obtained from natural sources such as guano and evaporites or manufactured via the Haber process; it is the oxidant in gunpowder (black powder) and an important agricultural fertilizer. Some Class D dry powder extinguishers designed for metal fires are also effective. [106], Potassium sodium tartrate (KNaC4H4O6, Rochelle salt) is a main constituent of some varieties of baking powder; it is also used in the silvering of mirrors. Radioactive Human Body", "Structural and thermodynamic properties of selective ion binding in a K+ channel", "Serum Potassium Levels and Mortality in Acute Myocardial Infarction", "The relationship between estimated sodium and potassium excretion and subsequent renal outcomes", "An Integrated View of Potassium Homeostasis", "Micropuncture study of nephron function in the rhesus monkey", "Experimental potassium depletion in normal human subjects. The number of protons in an atom. Block What Blood Pressure Medicine, that will NOT cause Weight Gain? It is also used to bleach textiles and straw, and in the tanning of leathers. Commercial use of the Images will be charged at a rate based on the particular use, prices on application. The mass of an atom relative to that of carbon-12. Hello, this week the story of the first alkaline metal ever isolated, why it's an alkaline metal at all and why its symbol begins with the letter K. Here's Peter Wothers.

The RSC has been granted the sole and exclusive right and licence to produce, publish and further license the Images. This is approximately the sum of the number of protons and neutrons in the nucleus. The role of the element in humans, animals and plants. It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids.
