Vedclass · Answer

(A) Ionization Enthalpy $(I.E.)$ is the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.Electron Affinity $(E.A.)$ is the amount of energy released when one electron is gained by an isolated gaseous atom.For the process $(i)$: $Cl + e^{-} \longrightarrow Cl^{-} \quad \Delta H = -E.A.$For the process $(ii)$: $Cl^{-} \longrightarrow Cl + e^{-} \quad \Delta H = +I.E.$Since these are reverse processes,the magnitude of energy involved is the same: $| I.E. 	ext{ of process } (ii) | = | E.A. 	ext{ of process } (i) |$.

Column $I$ (Element types)	Column $II$ (Electronic configuration)
$A$. Inert-gas elements	$1. (n-1)d^{1-10} ns^{1-2}$
$B$. Transition elements	$2. ns^2 np^6$
$C$. Inner-transition elements	$3. (n-2)f^{1-14} (n-1)s^2 p^6 d^{0-1} ns^2$
