Potassium Properties and uses of Potassium The boiling point for potassium is 1425°F Potassium has the melting point of 146°F A slivery color is what potassium looks like 19 is the correct atomic number for potassium Last but not least the density for potassium is 0.86 g.cm ˉ3 at 0°C Potassium is used in glass Also potassium is in soap It is in a lot of soils Potassium can be found in low sodium salt Last it is in just about every fertilizer Potassium takes up 2.4% of the Earths crust by weight Interesting Facts About Potassium The word potassium comes from the English word potash which means pot Ashes Potassium was discovered in 1807 It was found by an English man named Sir Humphrey Davy It is in high demand as a fertilizer Potassium is easily cut with a knife You can find this element in the earth’s crust A Song About Potassium (to the Brady Bunch Theme song) There is a story of a lovely element With nineteen protons and neutrons of its own And one day it met an atom With nineteen electrons of its own Potassium Yes it’s potassium That’s the way it became potassium Da da dadadum Used in glass Atomic Number 19 Symbol K Used as a fertilizer Uses Found in most soils Potassium Basic Info Used in soap Density is 0.86 g/cm At -3°C In England Atomic Weight 39.098 Discovered In 1807 Origin properties By Sir Humphry Davy Slivery Boiling point Is 1425°F Alkali Metal Melting point 146°F Obtained it Through the Electrolysis And very dry Molten Potash Sources http://www.webelements.com/webelements/s cholar/elements/periodic-table/uses.html http://www.chemicalelements.com/index.ht ml http://chemistry.about.com/library/blper5.ht m http://www.chemsoc.org/viselements/pages/ pertable_fla.htm http://chemistry.allinfoabout.com/periodic/per iodictable.html
