Electron affinity of noble gases is negligible. Explain.

Text Solution

Verified by Experts

Noble gases have completely filled electronic configuration, i.e., `ns^(2) np^(6)`. They do not have any tendency to gain or to lose electron. Thus, they have zero affinity for the incoming electron. Hence, electron affinity of noble gases is negligible.
