The Metals. The alkali metals, lithium (Li), sodium (Na), potassium (K), rubidium (Rb) and cesium (Cs), are all extremely light in weight, compressible, and relatively, very soft.Lithium is the hardest of the alkali metals with a hardness of 0.6 on Mohs' scale. Freshly cut surfaces of the alkali metals show a silvery white luster, which tarnishes quickly and becomes dull in air.

WebElements Periodic Table » Caesium » historical information

Caesium (cesium in USA) was discovered spectroscopically by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff in 1860 in samples of mineral water from Durkheim. Their identification was based upon two bright blue lines in the spectrum. The name caesium (from the Latin "caesius" - heavenly blue) was coined for its bright blue spectroscopic lines.
