Assign true $(T)$ and false $(F)$ for the following statements and select the correct option for your answer:
$(a) \, IP$ of $O_{(g)}$ is less than $IP$ of $O_{(g)}^{-}$
$(b) \, IP$ of $Ne_{(g)}$ is greater than $IP$ of $Ne_{(g)}^{+}$
$(c) \, EA$ of $O_{(g)}^{+}$ is greater than $EA$ of $O_{(g)}$
$(d) \, IP$ of $N_{(g)}$ is greater than $IP$ of $N_{(g)}^{+}$

Based on the provided image,identify the correct option for the elements $A, B, C, D, E$ given that $C$ has the electronic configuration $[Xe] \ 6s^2 \ 5d^1$.

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

List-$I$	List-$II$
$A$. $Al^{3+} < Mg^{2+} < Na^{+} < F^{-}$	$I$. Ionisation Enthalpy
$B$. $B < C < O < N$	$II$. Metallic character
$C$. $B < Al < Mg < K$	$III$. Electronegativity
$D$. $Si < P < S < Cl$	$IV$. Ionic radii

Choose the correct answer from the options given below:

State whether the following statements are true or false:
$(i)$ As the atomic number increases in a period,the nuclear charge increases,therefore the ionization enthalpy increases.
$(ii)$ As the metallic character of elements increases,the atomic radius generally increases.
$(iii)$ $Mn$ $(Z = 25)$ is a transition element. Although it is a $3d$-orbital element,its position in the periodic table is in the $4^{th}$ period.

Which one of the following sets of ions represents the collection of isoelectronic species?
