补充资料：Rb
元素符号Rb，原子序数37，原子量85.47，核外电子排布式3s23p63d104s24p65s1，在周期表中位于第五周期ⅠA族。原子金属半径247.5皮米(Pm)，离子半径147皮米，第一电离能405kJ/mol，电负性0.8，主要氧化数+1。银白色有金属光泽，质软，硬度为0.3，密度为1.532g/cm3(固)，1.475g/cm3(液)，熔点38.39℃，沸点688℃，电导性7.7。化学性质极活泼，在空气中很快形成氧化层而失去光泽并自燃生成深棕色的超氧化物RbO2。臭氧跟氢氧化铷反应可生成臭氧化铷，铷跟氯气或溴猛烈反应燃烧形成火焰，不跟氮气反应。铷跟水剧烈反应并发生爆炸，跟温度低于-100℃的冰也能发生剧烈的反应，生成氢气和氢氧化铷。跟氢气化合生成氢化铷。它是碱金属氢化物中最不稳定的一种，加热不待熔化即行分解，铷平时保存在煤油里。铷的蒸气在180℃时显绛红色，高于250℃时则变为橙黄色。铷有优异的光电性能，铷原子受光的照射时会激发释放出电子，利用这种特性，可把铷喷镀在银片上，制成光电管，广泛应用于电影、电视、自动控制设备中。由于铷能强烈地跟氧气化合，制造真空管时用做吸氧剂。铷汞齐用做催化剂。有些铷的化合物用于医药。1861年德国的本生和基尔霍夫，用光谱分析的方法从云母提取物中发现了铷，并根据谱线的颜色命名为铷(原意是暗红)。铷在自然界很少，而且分散，海水中含量较多，用重结晶法从海水中提取氯化铷。可用电解熔融氯化铷的方法制备铷，但有危险，工业上主要用钙或镁在700～800℃和真空条件下还原氯化铷制取铷。铷的沸点比钙低，便于分离收集。
