10. Periodic Properties of the Elements Periodic Trend: Electron Affinity
4PRACTICE PROBLEM
The electron affinity is the energy change from the addition of 1 e– to a gaseous element/ion. The trend for electron affinity increases from left to right and decreases down a period in the periodic table. However, nitrogen is an unusual element because it breaks this trend by having an electron affinity close to zero. Explain why nitrogen has an electron affinity close to zero.
