0The first and the second ionization enthalpies \( \left(\mathrm{kJ} \mathrm{mol}^{-1}\right) \) of three elements I, II and III are given below:
\begin{tabular}{|c|c|c|}
\hline Element & \( \Delta_{i} H_{1} \) & \( \Delta_{i} H_{2} \) \\
\hline I & 403 & 2640 \\
II & 549 & 1060 \\
III & 1142 & 2080 \\
\hline
\end{tabular}
Identify the element which is likely to be a non-metal
