Transcript of Potassium

Potassium (K) By: Kellie Shaw and Nathan Palmer the electrons in their correct energy levels everyday food items that potassium is abundant in. Physical and Chemical Properties of Potassium Color: Silvery white State of matter at room temperature: Solid Density (g/cc*): .856 Melting Point: 145.85 F Boiling Point: 1400 F Odor: No odor Texture: Soft Flammability: Potassium is very flammable when it is exposed to water. How reactive is it? It oxidizes rapidly when exposed to air and it spontaneously explodes when it is exposed to water. It combines with many nonmetal elements on the right side of the periodic table, including sodium (Na), chlorine (Cl), and oxygen (O). References *g/cc is grams/centimeters cubed. 1g/cc ≈ 1mL Type of Element: Alkali metal Periodic Table Information Atomic Number: 19 Atomic Weight: 39.0983 Period: 4 Group Number: 2A Family: Alkali metal potassium in water About Potassium Background history: Sir Humphry Davy of England discovered potassium in 1807. -Chemistry textbook Uses of Potassium Where potassium is found: Potassium cannot be found free in nature, however it is often found together with other elements. Potash* is mined in Germany, Utah, California, and New Mexico, in addition to other places, where it is then separated into raw potassium. How potassium is separated from other materials: Potassium is separated from other materials found with it through electrolysis*. Sir Humphry Davy Medical impact: One of the most important use of potassium is to treat the symptoms of hypokalemia.* -http://www.umm.edu/altmed/articles/potassium-000320.htm -http://chemistry.about.com/od/elementfacts/a/potassium.htm -http://www.thedailygreen.com/environmental-news/latest/potassium-superfoods-47020908 - http://www.mcvitamins.com/Vitamins/potassium.htm *Electrolysis: a process that involves forcing a current through a cell to cause a chemical reaction that would not otherwise occur. *Hypokalemia: deficiency of potassium in the bloodstream. *Potash is an alkaline potassium compound, especially potassium carbonate or hydroxide. -http://education.jlab.org/itselemental/ele019.html -Potassium is very common in our everyday lives. It is found (in abundance) in bananas, avocados, sweet potatoes, regular potatoes, orange juice, white beans, dates, yogurt, clams, raisins, and tomatoes. -Potassium is used by doctors as a way of keeping your body healthy. Consuming foods with potassium lowers the risk of a stroke, strengthens your bones, and decreases one's risk of death from a cardiovascular disease. It is also used as a preservative for beer and wine and used to stop the heart during surgery. Potassium chromate is used to tan leather, stain dye, and for use in fireworks. It is also a common ingredient in plant fertilizers. -http://www.ehow.com/about_4707285_what-potassium-used.html - Potassium is often found with other elements. Potassium chloride, potassium sulfate, and potassium nitrate are used in plant fertilizers. Potassium chloride is also used by doctors for heart surgery. Potassium nitrate is used to create glass that is stronger than ordinary glass. Potassium hydroxide a strong base, that is why it is used in industries and science laboratories. It is also used to make soap. -http://wanttoknowit.com/uses-of-potassium/
