Most often used as an electrical conductor. Also used in the manufacture of water pipes. Its alloys are used in jewelry and for coins. Pure copper occurs rarely in nature. Usually found in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides like cuprite (Cu2O). sWvp_Z2kfYs Copper
Potassium's symbol K comes from 'kalium' the name of the element in Germany and Scandinavia.

Potassium metal was first isolated in 1807 by Sir Humphry Davy, who derived it from caustic potash by the use of electrolysis of the molten salt with the newly discovered voltaic pile.

Potassium was the first metal that was isolated by electrolysis. از زبان انگلیسی: خاکستر - زبان لاتین: پتاسیم - زبان عربی 'قالی': قلیا 29 From the Latin word "cuprum" meaning the island of "Cyprus"

Potassium must be handled with great care with full skin and eye protection
People whose diets are low in potassium can suffer from hypokalemia
The greatest demand for potash has been in its use for fertilizers.

Potassium is an essential constituent for plant growth and is found in most soils.

Potassium nitrate is the main explosive ingredient in gunpowder.

Potassium hydroxide is used in the manufacture of soft soaps and as an electrolyte in alkaline batteries.
