萤石中含有卤族元素氟，是制取含氟化合物的主要原料，又由于熔点低而广泛用于炼钢、有色金属冶炼、水泥、玻璃、陶瓷。

A halogen element, f, is major raw materials deriving fluorine compound, and because of low melting point, that is widely used in steelmaking, nonferrous metal smelting, cement, glass and ceramics.

So they'd much rather just stay the way they are and not have another electron come on, and it turns out that halogens have the highest electron affinities.

所以它们更愿意保持在原来的状态,不愿意再增加一个电子,结果卤族元素具有最高的电子亲和能。
