Assign true ($\mathrm{T}$) or false ($\mathrm{F}$) for the following statements and select correct option for your answer.

($\mathrm{I}$) $\mathrm{IP}$ of $\mathrm{O}\left(\mathrm{g}\right)$ is less than $\mathrm{IP}$ of ${\mathrm{O}}^{-}\left(\mathrm{g}\right)$
($\mathrm{II}$) $\mathrm{IP}$ of $\mathrm{Ne}\left(\mathrm{g}\right)$ is greater than $\mathrm{IP}$ of ${\mathrm{Ne}}^{+}\left(\mathrm{g}\right)$
($\mathrm{III}$) $\mathrm{EA}$ of $\mathrm{Ne}\left(\mathrm{g}\right)$ is greater than $\mathrm{EA}$ of $\mathrm{O}\left(\mathrm{g}\right)$

($\mathrm{IV}$) $\mathrm{IP}$ of $\mathrm{N}\left(\mathrm{g}\right)$ is greater than $\mathrm{IP}$ of ${\mathrm{N}}^{+}\left(\mathrm{g}\right)$

($A$) ${\mathrm{M}}^{-}\left(\mathrm{g}\right)\to \mathrm{M}\left(\mathrm{g}\right)$

($B$) $\mathrm{M}\left(\mathrm{g}\right)\to {\mathrm{M}}^{+}\left(\mathrm{g}\right)$

($C$) ${\mathrm{M}}^{+}\left(\mathrm{g}\right)\to {\mathrm{M}}^{2+}\left(\mathrm{g}\right)$

($D$) ${\mathrm{M}}^{2+}\left(\mathrm{g}\right)\to {\mathrm{M}}^{3+}\left(\mathrm{g}\right)$

The minimum and maximum $\mathrm{I}.\mathrm{P}.$ would be of:

Consider the following ionisation steps:

$\mathrm{X}\left(\mathrm{g}\right)⟶{\mathrm{X}}^{+}\left(\mathrm{g}\right)+{\mathrm{e}}^{-}; \mathrm{\Delta H}=100 \mathrm{unit}$

$\mathrm{X}\left(\mathrm{g}\right)⟶{\mathrm{X}}^{2+}\left(\mathrm{g}\right)+2{\mathrm{e}}^{-}; \mathrm{\Delta H}=250 \mathrm{unit}$

Select the correct statement(s).

The ${\mathrm{IE}}_1$ of ${\mathrm{I}}^{\mathrm{st}}$ series of transition elements are as given:

From the above data, which of the following is not true?

The ${\mathrm{IE}}_1$ of ${\mathrm{I}}^{\mathrm{st}}$ series of transition elements are as given:

In general transition elements reacts:

$1{\mathrm{s}}^2,2{\mathrm{s}}^2,2{\mathrm{p}}^6,3{\mathrm{s}}^2,3{\mathrm{p}}^6,3{\mathrm{d}}^{\mathrm{n}},4{\mathrm{s}}^2\to 1{\mathrm{s}}^2,2{\mathrm{s}}^2,2{\mathrm{p}}^6,3{\mathrm{p}}^6,3{\mathrm{d}}^{\mathrm{n}}$

How do you explain the ionisation of transition elements?
