Question

Factors Effect Electron Gain Enthalphy

Answer 1

Answer:electron gain enthalpy is affected by

1) atomic size

2)Zeff of the nuclear charge

3)full filled and half filled electrons

Explanation:

1. Atomic size is inversely proportional to the electron gain enthalpy because we know that as the atomic size increases force of attraction of nucleus towards incoming electron decreases so electron gain enthalpy decreases

2. as Z effective increases force of attraction of nucleus towards incoming electron increases in electron gain enthalpy increases

3.in general electron affinity is very less for fulfilled and half filled in electronic configuration due to more stability
