Mercury is the only metal which is liquid at $0 \, ^{\circ}C$. This is due to its

The ionization energy will be higher when the electron is removed from

In the second period of the long form of the periodic table,an element $X$ has the second lowest first ionization enthalpy and element $Y$ has the second highest first ionization enthalpy values. What are $X$ and $Y$?

If the $IP$ of $Na$ is $5.48 \, eV$, the ionisation potential of $K$ will be ............ $eV$.

The first ionization enthalpy $(\Delta_{i} H)$ values of the third period elements,$Na, Mg$ and $Si$ are respectively $496, 737$ and $786 \, kJ \, mol^{-1}$. Predict whether the first $\Delta_{i} H$ value for $Al$ will be more close to $575$ or $760 \, kJ \, mol^{-1}$? Justify your answer.

Which one of the following statements is incorrect in relation to ionization enthalpy?
