Vedclass · Accepted Answer

Xenon

Vedclass · Answer

(A) Step $1$: Electron gain enthalpy is the energy change when an electron is added to a neutral gaseous atom.Step $2$: Noble gases like $Xenon$ $(Xe)$ have a stable $ns^2 np^6$ electronic configuration.Step $3$: Adding an electron to a noble gas requires energy to overcome the stability of the filled shell, resulting in a positive electron gain enthalpy.Step $4$: Halogens like $Bromine$, $Iodine$, and $Chlorine$ have high electron affinity and release energy upon electron gain, resulting in negative electron gain enthalpy.Step $5$: Therefore, $Xenon$ is the correct answer.
