- Greater the nuclear charge, more negative is the electron gain enthalpy
- Nitrogen has positive electron gain enthalpy
- Electron gain enthalpy decreases from fluorine to iodine in the group
- Chlorine has highest electron gain enthalpy with negative sign
Nitrogen has lower electron affinity than its preceeding element carbon because
Electron affinity decreases along a period
Electron affinity generally increases along a period
