Question

Noble gases have _____electron affinity
a) High
b) Low
c) Zero
d) Very low

Answer 1

Answer ⇒ Zero.  Option (c) 

Explanation ⇒ The amount of the energy released when the neutral isolated atom is converted into the negatively charged ions is called as the Electron affinity.
Since, noble gases are the stablest elements of the Periodic table which are present in the 18 groups. They do not combines as there octets are complete and hence due to the stablest configuration they have the zero electron affinity.  


Hence, Option (c) is correct.


Hope it helps.
