Nucleosynthesis of potassium

Supernova nucleosynthesis Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in These are called "primary elements", in that they can be fused from pure hydrogen and helium in massive stars. As a result of their ejection from supernovae, their abundances increase within the interstellar medium.

It is a chemical element with the atomic number 19 and is represented by the chemical symbol K.

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. Potassium is a highly reactive metal that is silvery-gray in appearance. It is a chemical element with the atomic number 19 and is represented by the chemical symbol K. It was discovered and first isolated by Humphry Davy in Potassium is formed by the nucleosynthesis of lighter atoms, which mostly occurs in Type II supernovas. Big Bang nucleosynthesis occurred within the first three minutes of the beginning of the universe and is responsible for much of the abundance of 1 H, 2 H (D, deuterium), 3 He, and 4 He.

In fact, it is the 17th most common element on the planet and 20th most common in the solar system. All naturally occurring potassium consists of three isotopes, but many others have been identified.

Stellar Evolution

How many isotopes does potassium have? The three naturally occurring isotopes of potassium are 39K, 40K and 41K. It does have a very long half life and eventually decays to 40Ar and 40Ca. There are also 22 other isotopes of potassium that have been identified.

All of these isotopes are unstable and have half lives of less than a day. Most of these isotopes have half lives of less than a second. The most unstable potassium isotopes are 33K and 34K, which have half lives of less than 25 nanoseconds!

It can be used to date rocks and as a tracer in the study of weathering. It is also used in school studies as a radioactive source. It is also found in plants, animals and humans and is the largest natural source of radioactivity in the human body.

Foods high in potassium, such as bananas, contain this naturally occurring radioactive potassium yes bananas are radioactive!

A truck load of bananas can actually create a false alarm when scanned by a Radiation Portal Monitor. Despite this, foods containing potassium are perfectly safe and there is no need to be alarmed!Theoretically, it is natural that the odd-Z element, potassium decreases with lower metallicity, and thus, the observation should imply new and unknown sites for potassium.

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.

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.
