Rb is a kind of chemicals, extremely soft waxy white metal. Soft and light, and its chemical properties than potassium and lively. Under the action of light, easy to emit electrons. Dramatic effect, under the influence of water to generate hydrogen and hydroxide rb. Easy and oxygen generating complex oxides. Due to the reaction under the influence of water release large amounts of heat, so can make hydrogen combustion immediately. Pure metal rubidium is usually stored in a sealed glass ampoules.
The nature of the rubidium between the cesium potassium and the bottom of the above, the nature is very lively, in the air immediately lose metallic luster, violently by the oxygen oxidation, and can cause rubidium spontaneous combustion. Reactions under the influence of water is very severe, or even access to - 100 ℃ below the ice will be an explosion.
