Potassium(K) is the 8th most abundant elements in the Earth’s Crust and it makes up roughly 2.1% of the Earth’s crust. Potassium is an alkali metal and is a soft and metallic solid with a high electrical and thermal conductivity. Its atomic number is 19 and was isolated by Sir Humphry Davy in 1807 after using a process called electrolysis on potash (potash is an alkaline potassium compound). Potassium is a highly reactive metal because of its low ionization value.
In nature, potassium is difficult to obtain in a pure metallic state because it is far too reactive. In nature, potassium is usually found in minerals, rocks and compounds. minerals and rocks such as granite, pumice, obsidian, gneiss, schist, feldspars, muscovite and sylvite all contain Potassium. Potassium can also be found as a caption. A caption is when a metal is positively charged because it loses a few of its electron.
Potassium is hard to obtain in its pure metallic state and is usually found as a compound, a mineral or a rock. To extract the potassium from a compound, an increase of energy must be added. This process to extract potassium from a compound is called electrolysis. Electrolysis is when a compound is broken down into its different elements by electricity. The potassium compound is melted, and then electricity is passed on through the melted compound to split the elements. In The main sources of Potassium are mined in Russia, Canada, Germany, Israel, France and the USA.
The physical properties of potassium are that its pure solid form is a silvery-white, malleable metal with a melting point of 63.5°C and a boiling point of 759°C. potassium also has a vii
