Cesium is an alkali metal, like sodium; hence, it forms a salt, cesium chloride ([math]CsCl[/math]) similar to table salt, sodium chloride. CsCl looks like most salts: It's worth noting that the formation of salts is highly exothermic, that is, if you were to get cesium metal and gaseous chlorine to combine to form this salt, the reaction would ...

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.
