Text Solution
Verified by ExpertsThe correct answer is:
A
at absolute zero temperature. The electron gain enthalpy 
could be positive endothermic or negative exothermic. If 
has high negative values, more is the stability of 
. In case of 
value is les negative compared to other elements present in their corresponding groups. However, 
greater negative value than 
due to the larger size of 
, less interelectronic repulsion than 
. So, 
in terms of stability.
The correct order :
