The first\[({{\Delta }_{i}}{{H}_{1}})\]and second\[({{\Delta }_{i}}{{H}_{2}})\]ionisation enthalpies (in\[kJ\text{ }mo{{l}^{-1}}\]) and the\[({{\Delta }_{eg}}H)\]electron gain enthalpy (in\[kJ\text{ }mo{{l}^{-1}}\]) of the elements I, II, III, IV and V are given below

Element	\[{{\Delta }_{i}}{{H}_{1}}\]	\[{{\Delta }_{i}}{{H}_{2}}\]	\[{{\Delta }_{eg}}H\]
I	520	7300	\[-\,60\]
II	419	3051	\[-\,48\]
III	1681	3374	\[-\,328\]
IV	1008	1846	\[-\,295\]
V	2372	5251	\[+\,48\]
