Question

Describe the trend of electron affinity along a period. ​

Answer 1

Answer:

Electron affinity generally increases across a period in the periodic table and sometimes decreases down a group. These trends are not necessarily universal. The chemical rationale for changes in electron affinity across the periodic table is the increased effective nuclear charge across a period and up a group.
