What is the nature of electron gain enthalpy and ionisation enthalpy in noble gases and noble metals?

Expert Answer:

Dear Student,
When an atom gains an electron it releases energy which is called electron gain enthalpy or electron affinity. It's value is negative.

Noble gases/metals have stable electronic configuration. Therefore they have no tendency to accept the electron and therefore, have large positive value of electron gain enthalpy.

We hope that clarifies your query.
