At first it may seem rather strange to treat the chemistry of the halogens and the noble gases,two groups that represent the extremes of chemical activity and inertia ,in the same section .the superficial differences between the halogens and the noble gases are much reduced,however if we focus our attention on the comparison of halide ions(particularly F-) with the isoelectronic noble gas atoms and the noble gas compounds with halogen atoms or the halogens in their higher positive-oxdation states.

起初它可能看起来很奇怪对待的卤素化学和惰性气体，两个团体代表在同一节的化学活性和惯性的极端。与卤素和惰性气体的表面差异大大减少，但是，如果我们着眼于（特别是架F -等电子与惰性气体原子和原子与卤素或在卤素稀有气体化合物）卤离子的比较，我们的注意力较高的正- oxdation国家。
