The first `(Delta_(i)H_(1)` and second `(Delta_(i)H_(2)` ionization enthalpies (in kJ/mol) and electron gain enthalpy (in kJ/mol) of few elements are given below: `{:("Elements",Delta_(i)H_(1),Delta_(i)H_(2),Delta_(eg)H),(I,520,7300,-60),(II,1681,3374,-328),(III,899,1757,+48),(IV,2372,5251,+48):}` Which of the following is likely to be an alkali metal?A. I and IVB. V and IIC. II and VD. IV and V |
