  1. Lithium by: Jimmy Della Femina

  2. Discovery - Discovered by Swedish Chemist Johan August Arfwedson - Arfwedsonis given credit for the discovery after identifying it in 1817 Arfwedsonfound lithium in a mineral that has just been discovered, petalite Petalite was discovered by Brazilian scientist Joze Bonifacio de Andrada e Silva Naming Named Lithium after the Greek word for stone, “lithos” HowitwasDiscovered Arfwedson studied petalite but found that he could not identify 10% of the mineral. The missing 10% was then identified as a new element Arfwedson did not ever get lithium to its purest form. Years later, William Thomas Brande was able to separate lithium into a pure form. History of Lithium

  3. Physical Properties Melting Point: 180.54 Boiling Point : 1,335 Density: 0.534 g/cm Atomic Mass: 6.941g Flammable Solid Silvery-White Lightest weight of all Metals Chemical Properties Reacts slowly with water at room temperature Faster reactions as temperature rises Reacts with most acids and gives off hydrogen Combines with Sulfur, Hydrogen, Nitrogen, and Halogens Characteristics

  4. Sources of Lithium • Around 0.005% of earth’s crust abundance is lithium • Found in spodumene, petalite, and lepidolite. • Also is released when salt water evaporates • Ores are found in mines such as Silver Peak in Nevada • Extracted by way of electrolysis

  5. Used to produce aluminum and other substances in stronger forms In the past, lithium was used to make black and white tube televisions and tupperware Lithium Stearate Mixed with petroleum producing thick grease for lubrication Doesn’t break down at high temperatures Doesn’t become hard when cooled No reaction with water or oxygen Used in the military, vehicles, cosmetics, plastics, aircrafts, marine technology, and much more. Lithium Batteries Converts chemical energy into electric energy Lighter than lead and sulfuric acid batteries and less toxic Used in many small appliances, watches, electrons, etc. Also used in advanced satellites today Health Benefits Used as treatment for maniac/depressive disorders such as bipolar Interferes with neurotransmitters Increases production of white blood cells Has very few side effects Uses of Lithium
