SET-A	SET-B
1) Electron affinity	A) $s>p>d>f$
2) Second IE	B) $23.06k.cal/mole$
3) Penetration power	C) $Ag\left(g\right)+e^{-}\to A^{-}\left(g\right)+E{A}_1$
4) 1 ev/atom	D) $M^{+}\left(g\right)\to M^{2+}\left(g\right)+e^{-}$

For $\text{A}\to \text{R}$: When an electron is added to the gaseous atom to convert into a negative ion,  the enthalpy change accompanying the process is known as the electron gain enthalpy.

FOR $\text{B}\to \text{S}$ : Addition of second electron in an atom is more difficult and energy is needed to overpower the repulsion forces between negatively charged atomic sphere and the valence electrons. This energy being greater than energy released during gaining of electron.

$\text{C}\to \text{P}$:The ionization potential also depends on the sub shell in which the electron is present. the penetration power of s,p,d,f subs hell  is  s > p > d > f.

$\text{D}\to \text{Q}$ : 1Ev/atom=23.06kcal/mol=96.39kj/mol.
