Question

04. Noble gases and Nitrogen have positive electron gain enthalpy values. Explain​

Answer 1

Answer:

The electron gain enthalpy for halogens is highly negative because they can acquire the nearest stable noble gas configuration by accepting an extra electron. Noble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels.

Answer 2

Answer:

I hope this will help you

Explanation:

noble gas and nitrogen have positive electron gain enthalpy because the electron has to enter the next higher Principal Quantum level leading to unstable electronic configuration
