${\mathrm{N}}_0/2$ atoms of $\mathrm{X}(\mathrm{g})$ are converted into ${\mathrm{X}}^{+}(\mathrm{g})$ by energy ${\mathrm{E}}_1.{\mathrm{N}}_0/2$ atoms of $\mathrm{X}(\mathrm{g})$ are converted into ${\mathrm{X}}^{-}(\mathrm{g})$ by energy ${\mathrm{E}}_2$. Hence, ionization potential and electron affinity of $\mathrm{X}(\mathrm{g})$ are: ( ${\mathrm{N}}_0$ is Avogadro Number)
