What is the origin of the name for lithium?

ok i have a science project on lithium due tomorow and 1 of the required ? is the origin of the name so .... HELP!!!!

What is the origin of the name for lithium?
Petalite, which has lithium in it, was discovered by the Brazilian scientist Jos茅 Bonif谩cio de Andrade e Silva in the late 1700s on a trip to Sweden. Lithium was discovered by Johan August Arfwedson in 1817. Arfwedson found the new element within the minerals spodumene and lepidolite in a petalite ore (LiAl(Si2O5)2) that he was analyzing during a routine investigation of some minerals from a mine on the island Ut枚 in Sweden. In 1818 Christian Gmelin was the first to observe that lithium salts give a bright red color in flame. Both men tried and failed to isolate the element from its salts.





The element was not isolated until William Thomas Brande and Sir Humphry Davy later used electrolysis on lithium oxide in 1818. Robert Bunsen and Matiessen isolated larger quantities of the metal by electrolysis of lithium chloride in 1855. Commercial production of lithium metal was achieved in 1923 by the German company Metallgesellschaft through using electrolysis of molten lithium chloride and potassium chloride. It was apparently given the name "lithium" (Greek 位喂胃o蟼 (lithos), meaning "stone") because it was discovered from a mineral while other common alkali metals were first discovered from plant tissue.
