金属铷 Metallic Rubidium
化学符号/chemical symbol:Rb
CAS号/CAs Number: 7440-17-7
铷的性质/Properties of Rubidium
铷是银白色稀有碱金属，质软而呈蜡状，密度约0.86克/立方厘米,熔点为39.31摄氏度，沸点为1113摄氏度，其化学性质活泼，在光的作用下易放出电子，遇水起剧烈反应，易与氧作用生成复杂的氧化物。
Rubidium is a silvery-white, rare alkali metal.
It is soft and waxy in texture, with a density of approximately 0.86 g/cm .
Its melting point is 39.31°c, and its boiling point is 1113°c. lt is highly reactive chemically, readily emitting electrons under light exposure. it reacts violently with water and readily forms complex oxides with oxygen
金属铯 Metallic Cesium
化学符号/chemical symbol:cs
CAS号/CAS Number:7440-46-2
铯的性质/Properties of cesium
铯是淡金色稀有碱金属，它的表面可能会因氧化而呈现灰色或黑色,密度约0.96克/立方厘米,熔点为28.44摄氏度沸点为671摄氏度。铯具有高度的活性,非常容易自燃，除了在空气中能够自发燃烧以外，铯在很低温度下就能够与水发生爆炸性的反应,比碱金屈中的其他元素更剧烈。铯可以在汽度低达-116″c的条件下与冰发生反应，由于其高度活性,该金属被分类为危险性物质。
Cesium is a pale gold-colored rare alkali metal. lts surface may appear gray or black due to oxidation. it has adensity of approximately 0.96 g/cm , a melting point of 28.44 ‘c, and a boiling point of 671 °c. cesium exhibitsextreme reactivity and spontaneously ianites, Bevond spontaneous combustion in air, it undergoes explosivereactions with water at extremely low tem peratures-more violently than any other alkali metal, Cesium react.with ice at vaporlpressures as low as -116’c, Due to its high reactivity, this metal is classified as a hazardoussubstance.
