The first ionisation energy of lithium $(Li)$ will be

In which of the following electronic configurations will there be a large difference between the second and third ionization energy?

The first ionisation potential of $Na$,$Mg$,$Al$ and $Si$ are in the order :-

Match List-$I$ with List-$II$:

List-$I$ (Electronic configuration)	List-$II$ ($\Delta_{i}H$ in $kJ\ mol^{-1}$)
$(a)$ $1s^{2} 2s^{2}$	$(i)$ $801$
$(b)$ $1s^{2} 2s^{2} 2p^{4}$	$(ii)$ $899$
$(c)$ $1s^{2} 2s^{2} 2p^{3}$	$(iii)$ $1314$
$(d)$ $1s^{2} 2s^{2} 2p^{1}$	$(iv)$ $1402$

Choose the most appropriate answer from the options given below:

If first ionization enthalpy $(\Delta_i H)$ values of $Na$,$Mg$ and $Si$ are respectively $496$,$737$ and $786 \ kJ \ mol^{-1}$,the first ionization enthalpy value of $Al$ (in $kJ \ mol^{-1}$) will be

The correct option for the first ionisation enthalpy (in $kJ \ mol^{-1}$) of $Li$,$Na$,$K$ and $Cs$ respectively is
