Legend

Name origin:	Greek: lithos (stone)
Description:	Soft silvery-white metal. Lightest of metals. Accounts for only 0.0007% of the earth's crust.
Discovered by:	Johann Arfwedson
Year:	1817
Place:	Sweden
Sources:	Obtained by passing electric charge through melted lithium chloride and from the silicate mineral called spodumene [LiAl(Si2O6)].
Use(s):	Used in batteries. Also for certain kinds of glass and ceramics. Some is used in lubricants.
