摘 要:
本诗介绍了氟、氯、溴、碘四个常见卤族元素的性质。诗歌主要强调了四个卤族元素的外层电子排布导致的与碱金属的强反应活性,从而使卤族元素得到一个电子,通过形成离子键来达到与同周期惰性气体一致的外层电子排布。诗歌中还穿插了一些卤族元素的应用领域,如除草、灭火、消毒等。
关键词:卤族元素;卤素的应用;电子排布;碱金属
Abstract:
The poem introduces the properties of four common halogens: Fluorine, Chlorine, Bromine and Iodine. The emphasis of this poem is the elements’ high reactivity with alkali metals due to their outer electronic configuration. This special configuration leads to their tendency of gaining one electron from the alkali metals to form the same kind of electronic configuration as the noble gases in their periods. Some applications of these elements, such as weeding, fire extinguishing and sterilization, are also integrated into the poem.
Keywords: Halogens; Applications of halogens; Electronic configurations; Alkali metals
