Used as an alloy with iron and nickel. It can be used in nuclear reactors and is known to be superconductive when alloyed with tin, aluminum or zirconium. Occurs in a mineral columbite. Formerly known as colombium (Cb). It is used in stainless steel alloys for nuclear reactors, jets and missiles. Mr2hnIheDxQ Niobium
Lithium was discovered by Johann Arfvedson in 1817 when he was analyzing minerals from the island of Uto in Sweden.

The pure metal was isolated the following year by both Swedish chemist William Thomas Brande and English chemist Sir Humphry Davy working independently.

In 1855, larger quantities of lithium were produced through the electrolysis of lithium chloride by Robert Bunsen and Augustus Matthiessen. From the Greek word lithos, stone 41 1801 Charles Hatchett England From the Greek word "Niobe" meaning "daughter of Tantalus"
