Lightest of metals. Accounts for only 0.0007% of the earth's crust. Used in batteries. Also for certain kinds of glass and ceramics. Some is used in lubricants. Obtained by passing electric charge through melted lithium chloride and from the silicate mineral called spodumene [LiAl(Si2O6)]. MwH0796IN48 Lithium
Mendelevium was discovered by Albert Ghiorso, Glenn T. Seaborg, Gregory R. Choppin, Bernard G. Harvey and Stanley G. Thompson in 1955 at the University of California, Berkeley.

It was produced by the bombardment of einsteinium with helium.

Mendelevium was identified by chemical analysis in an ion exchange experiment. Named after Dmitri Mendeleev, who created the Periodic Table 3 1817 Johan August Arfvedson Stockholm, Sweden From the Greek word "lithos" meaning "stone"
