Question

Why noble gases have largest positive electron gain enthalpies in their respective period ??

Answer 1

as they have their complete octet... thus energy required to accept electrons is less actually there is no need for accepting electrons thus it's electron gain enthalpy is more

Answer 2

HELLO buddy here's ur answer,,,

.⏹⏹noble gases have largest positive electron gain enthalpies in their respective period,,

because as we from right to left , in the periodic table we generally, know that Electron gain ENTHALPY increases,,, hence as we go LEFT , Electron gain ENTHALPY increases, due to the Electron affinity of non metals...
