Facts about the Definition of the Element Potassium
The Element Potassium is defined as...
A soft, silver-white, highly or explosively reactive metallic element that occurs in nature only in compounds. It is obtained by electrolysis of its common hydroxide and found in, or converted to, a wide variety of salts used especially in fertilizers and soaps. A Potassium Reaction involves a process in which Potassium is mixed with another substance which react to form something else.

Interesting Facts about the Origin and Meaning of the element name Potassium
What are the origins of the word Potassium ?
The name originates from Potash and it's symbol - K - comes from the Latin word Kalium.


Facts about the Classification of the Element Potassium
Potassium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity.

Brief Facts about the Discovery and History of the Element Potassium
Potassium was discovered by Sir Humphrey Davy in 1807. This alkali metal was the first metal that was isolated by electrolysis.

Occurrence of the element Potassium in the Atmosphere
Makes up about 2.4% of the weight of the Earth's crust
Seventh most abundant element
Found in ancient lakes and seas
Mined in USA, Germany & New Mexico
Density less than that of water
Rapidly oxidises in air

Common Uses of Potassium
Substitute for table salt
Potassium nitrate, chloride & permanganate

Facts and Info about the element Potassium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Potassium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Potassium was discovered by Sir Humphrey Davy in 1807. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Potassium is just one element that can be found.
