According to the general trend in electron affinities, halogens tend to form the most stable anions in the gas phase. This is because halogens have a high electron affinity due to their close proximity to a noble gas configuration in terms of electron configuration. As a result, halogens readily accept an extra electron to form stable negative ions.
