Question

why noble gases have zero electron affinity ​

Answer 1

Noble gas elements have completely filled outer-shell. Such electronic configurations are highly stable and as such noble gases find it difficult to accept electrons. Thus electron affinity of noble gas elements is zero.

Answer 2

Answer:

Explanation:

Noble gas elements have completely filled outer -shell such electronic configurations are highly stable and as such noble gases find it difficult to accept electron's thus electron affinity of noble gas elements is zero. electron affinity of noble gas is near zero. noble gas has completely filled valence shells and octets. it does not accept electrons easily as they have no deficiency also adding electrons produces repulsion between the electrons. Electron affinity of an element is the energy released when an element in the gas phase gains an extra electron to from an anion
