Project on Potassium.

Extracts from this document...

Introduction

________________ Potassium (k) ________________ Basic Information ________________ Potassium is the 19th element on the periodic table of elements with, as suggested on the table has the atomic number of 19 and its atomic mass is 39.0983. The symbol used to represent Potassium and also used in equations is ?K?. Periodic table symbol of potassium. Atom number is top left, atomic mass is top right and symbol in the middle. ________________ Details and further information ________________ Potassium was discovered in 1807 but was speculated to exist as far back as 1702. Humphrey Davy born in Penzance, Cornwall in the UK was a British chemist who was also an inventor who discovered many other elements as well most notably sodium derived and separated potassium from caustic potash an artificial compound. ...read more.

Middle

It is usually found in its element form in nature because of its reactive properties. It can bond with other compounds to form Silvite, the mineral form of Potassium Chloride and Feldspar, the mineral which make up as much as 60% of the Earth's crust. Other interesting properties are that potassium is the second densest element before lithium and when left to exposure of air, its colour fades to grey. Potassium in its metal state. ________________ Chemical Properties ________________ Potassium is a very reactive metal and particularly reactive towards oxygen or water. When mixed with either 2 it changes into potassium hydroxide (water) and potassium peroxide (oxygen) and will light on fire. To stop potassium from reacting with air or water it?s put in kerosene where it can does not react and can be easily separated for use and also protected. ...read more.

Conclusion

Potassium nitrate makes the heads of matches and pyrotechnics (it is the major component of gunpowder.) Potassium hydroxide can be found in soaps, detergents and drain cleaners. Potassium carbonate or pearl ash is a product of ammonia that can be found in certain types of soap and glass. ________________ Little known Facts ________________ 1. Pure potassium is a lightweight silvery metal that is soft enough to cut with a knife. 2. The potassium ion is important for all living cells. Animals use sodium ions and potassium ions to generate electric potentials. This is vital for many cellular processes and is the basis for the conduction of nerve impulses. 3. Potassium compounds emit a lilac or violet flame color when burned. 4. Potassium is used as a heat transfer medium. Its salts are used as a fertilizer, oxidizer, colorant, to form strong bases, as a salt substitute, and for many other applications. ________________ ________________ Drawing of the Element.

    Food should be seasoned only with pepper or herbs in order to reduce salt intakes to recommended levels, said Martin Wiseman, a medical and scientific advisor for the World Cancer Research Fund. Adults should eat no more than six grams of salt a day but, on average, Britons actually consume more than nine.
