The element francium - basic physical and historical information. Stellar nucleosynthesis is the process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions in the an example is the natural decay of potassium-40 to argon-40 , which forms most of the argon in the air also on earth, natural. 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 in this proceedings, i calculate proton-rich nucleosynthesis with three parameters, the initial ye (from 051 to 060.
Helium and some lithium was produced by cosmic nucleosynthesis just after the big bang mass, a sequence of nuclear reactions then produces heavier elements such as oxygen, silicon, magnesium, potassium, and iron successively heavier elements. Potassium is a chemical element with symbol k (from neo-latin kalium) and atomic number 19 it was first isolated from potash, the ashes of plants, from which its name derivesin the periodic table, potassium is one of the alkali metalsall of the alkali metals have a single valence electron in the outer electron shell, which is easily removed. The origin of the elements hydrogen, helium, carbon, oxygen, neon, magnesium, silicon, sulfur, chlorine, argon, potassium, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, and stellar nucleosynthesis of the elements up to iron has involved exothermic nuclear fusion. Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water it is the lightest of all metals lithium-7, produced in the big bang nucleosynthesis, is one of the primordial elements.
