You are given Avogadro's number of "X" atoms. If half of the atoms of X transfer one electron to other half of 'X' atoms, 409 KJ must be added. If these \[{{X}^{-}}\] ions are subsequently converted to \[{{X}^{+}}\] , an addition 733 KJ must be added. Calculate IP of X in eV. Use \[(1eV=1.602\times {{10}^{-19}}\,J\,\,and\,\,{{N}_{A}}=6.023\times {{10}^{23}})\]
