When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.
It took decades to tease out the truth of Debereiner's conjecture, and thus to construct the periodic table-in which the alkali metals form the first column.
As far as the eye can reach stretches the great flat plain-land, all dusted over with patches of alkali, and intersected by clumps of the dwarfish chaparral bushes.
ONE of the first inklings that chemistry has an underlying pattern was the discovery, early in the 19th century, of lithium, sodium and potassium-known collectively as the alkali metals.
