It describes trends where electron affinities be...This page explains electron affinity as the energy released when an atom gains an electron, typically measured in negative values in the gaseous state. It describes trends where electron affinities become more negative across a period and less negative down a group, highlighting halogens as having the highest affinities due to their stable electron configurations. The text also acknowledges some exceptions to these trends.
