我想問有關化學的問題

Among fluorine, chlorine and bromine, bromine has the highest boiling point. All of the three halogens exist as diatomic molecules, which are held together by van der Waals’ forces (intermolecular forces). The van der Waals’ forces increase as the increase in molecular size. Since bromine has the greatest molecular size among the three halogens, thus bromine has the strongest van der Waals’ forces between the molecules, and thus the highest boiling point.

在氟、氯、溴三者中，溴的沸點最高。這三個鹵素均以雙原子分子存在，分子間以范德華引力（分子間引力）連在一起。范德華力隨分子體積而增強。由於在這三個鹵素中，溴的分子最大，所以分子間的范德華引力最強，因而沸點最高。

Bromine有最高的boiling point
因為 Fluorine, Chlorine and Bromine 都是halogen
而halogen的boiling point 由上而下遞增.
