Lithium is a member of the alkali group of metals. It has the highest specific heat of any material and the highest electrochemical potential. This makes it important in applications involving heat transfer and as the anode in batteries. Lithium is a dopant in advanced optical glass. It is used as an alloy in light weight metals. Lithium stearate is a common high temperature lubricant.
Lithium is a Block S, Group 1, Period 2 element. The electronic configuration is [He] 2s1. In its elemental form lithium's CAS number is 7439-93-2. The lithium atom has a radius of 152.pm and it's Van der Waals radius is 182.pm.
Lithium was first discovered by Johann Arvedson in 1817.
