Statement $I$ : The correct order of first ionization enthalpy values of $\mathrm{Li}, \mathrm{Na}, \mathrm{F}$ and $\mathrm{Cl}$ is $\mathrm{Na}<\mathrm{Li}<\mathrm{Cl}<\mathrm{F}$.
Statement $II$ : The correct order of negative electron gain enthalpy values of $\mathrm{Li}, \mathrm{Na}, \mathrm{F}$ and $\mathrm{Cl}$ is $\mathrm{Na}<\mathrm{Li}<\mathrm{F}<\mathrm{Cl}$
In the light of the above statements, choose the correct answer from the options given below :
$(I)\,[Xe]\, 6s^1$ $(II)\,[Xe]\,4f^{14}\,5d^1\,6s^2$
$(III)\,[Ar]\,4s^2\,4p^5$ $(IV)\,[Ar]\,3d^7,\,4s^2$
Select the incorrect statement about these elements
