A. reactive B. stable C. inert D. non-reactive 相关知识点: 试题来源: 解析 A。原因:文中提到“the alkali metals in Group 1 are all very reactive and have one valence electron.”,即第一组的碱金属都非常活泼且有一个价电子。反馈 收藏 ...
第十一章 Group 1 the alkali metals 中的卤化物MX部分指出，这些金属与卤素直接反应生成MX型卤化物，通常伴随负生成焓，但其生成焓趋势因元素不同而异。碱金属氟化物的生成焓变化与氯、溴、碘化物相反，这可用伯恩-哈伯循环解释。卤化锂具有高晶格能且仅微溶于水，而锂的其他卤化物在特定有机溶剂如THF...

Inorganic Chemistry(by Catherine Hous)笔记:第十一章 Group 1 the alkali metals 第IA族 碱金属(2) 11.5 Halides 卤化物 MX型卤化物是通过这些元素的直接化合而制备的,所有的卤化物都有很大的负的生成焓值。其递变顺序有所不同,可以通过下表看出,碱金属氟化物的生成焓变化趋势与氯、溴、碘化物的变化趋势有所不...
An alternative way of depicting the bonding, that underlines its relationship to the three-centre bonding of alkyl bridge bonds (and the number of electrons involved), is to show a two-centre link between the alkene carbon atoms and a three-centre link between them and the main group metal ...
