Electronic configuration of some elements is given
P in Column I and their electron gain enthalpies are

W given in Column II. Match the electronic configuration with electron gain enthalpy.
\( \begin{array}{ll}\text { Column (I) } & \text { Column (II) } \\ \text { Electronic } & \text { Electron Gain } \\ \text { configuration } & \text { Enthalpy/kJ mol }{ }^{-1} \\ \text { (1) } 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} & (\mathrm{P})-53 \\ \text { (2) } 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{~s}^{1} & (\mathrm{Q})-328 \\ \text { (3) } 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{5} & (\mathrm{R})-141 \\ \text { (4) } 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{4} & (\mathrm{~S})+48\end{array} \)
