Nucleosynthesis of potassium

Elemental potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with watergenerating sufficient heat to ignite the hydrogen emitted in the reaction. Because potassium and sodium are chemically very similar, it took a long time before their salts were differentiated.

Nucleosynthesis :D by Alicia Wong on Prezi

The existence of multiple elements in their salts was suspected from[1] and this was proven in when potassium and sodium were individually isolated from different salts by electrolysis. Potassium in nature occurs only in ionic salts.

As such, it is found dissolved in seawater which is 0. Most industrial chemical applications of potassium employ the relatively high solubility in water of potassium compounds, such as potassium soaps. Potassium metal has only a few special applications, being replaced in most chemical reactions with sodium metal.

Potassium ions are necessary for the function of all living cells.

Nucleosynthesis of potassium

Potassium ion diffusion is a key mechanism in nerve transmission, and potassium depletion in animals, including humans, results in various cardiac dysfunctions.

Potassium is found in especially high concentrations within plant cells, and in a mixed diet it is mostly concentrated in fruits. The high concentration of potassium in plants, associated with comparatively low amounts of sodium there, resulted in potassium's being first isolated from potashthe ashes of plants, giving the element its name.The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning.[2] Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.

Are sulfur and phosphorus also created in the nucleosynthesis of big stars? up vote 6 down vote favorite. There are as far as I know two fusion reactions by which stars convert hydrogen to helium: The CNO cycle (for carbon–nitrogen–oxygen) and the proton–proton chain reaction.

The elements created in the CNO cycle are C,N,O and Fluor.

Discussion

The other elements are created in stellar cores, through nucleosynthesis (nuclear fusion). Oxygen burning and silicon burning can lead to potassium: "The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning.

A. Stellar nucleosynthesis is a normal process that happens during the life cycle of stars. B.

[BINGSNIPMIX-3

Stellar nucleosynthesis is the term for the process by which stars create intermediate-weight elements. C. Stellar nucleosynthesis produces heavy elements with atomic numbers greater than iron. Sep 28,  · "Supernova nucleosynthesis" is a theory of the production of many different chemical elements in supernova explosions, first .

Supernova nucleosynthesis The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning. [2] Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.
