potassium is formed in supernovae by nucleosynthesis from lighter atoms. potassium is principally created in type ii supernovae via an explosive oxygen-burning process. is also formed in s-process nucleosynthesis and the neon burning process.









































potassium is the 20th most abundant element in the solar system and the 17th most abundant element by weight in the earth. it makes up about 2.6% of the weight of the earth's crust and is the seventh most abundant element in the crust. the potassium concentration in seawater is 0.39g/l (0.039 wt/v%), about one twenty-seventh the concentration of sodium.

potassium
sodium and potassium are very abundant in earth, both being among the ten most common elements in earth's crust; sodium makes up approximately 2.6% of the earth's crust measured by weight, making it the sixth most abundant element overall and the most abundant alkali metal. potassium makes up approximately 1.5% of the earth's crust and is the seventh most abundant element. sodium is found in many different minerals, of which the most common is ordinary salt (sodium chloride), which occurs in vast quantities dissolved in seawater. other solid deposits include halite, amphibole, cryolite, nitratine, and zeolite. many of these solid deposits occur as a result of ancient seas evaporating, which still occurs now in places such as utah's great salt lake and the dead sea. despite their near-equal abundance in earth's crust, sodium is far more common than potassium in the ocean, both because potassium's larger size makes its salts less soluble, and because potassium is bound by silicates in soil and what potassium leaches is absorbed far more readily by plant life than sodium.
