16 Question (1 point) @ See page 376 Electron affinities are experimentally determined by adding electrons to gas phase atoms or ions and measuring the exothermicity or endothermicity of the reaction. Electron additions that increase electron configuration stability and ion stability should yield greater exothermic values. 3rd attempt Ini See Periodic Table O See Hint If the reason explains why some elements have large exothermic electron affinities, place it the box marked "EA> 0" (EA = electron affinity). If the...
