Which of the following orders is correct according to the given property?

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.

Match the following elements with their respective blocks in the periodic table based on their atomic number $(Z)$:

Column-$I$	Column-$II$
$A. Z = 37$	$P. p-$ block
$B. Z = 42$	$Q. f-$ block
$C. Z = 34$	$R. d-$ block
$D. Z = 92$	$S. s-$ block

Which of the following statements regarding the block classification of elements with atomic numbers $(Z)$ is correct?

Nitrogen has positive electron gain enthalpy whereas oxygen has negative. However,oxygen has lower ionisation enthalpy than nitrogen. Explain.

Which of the following statements are correct for the classification of elements?
$I$. The properties of elements are periodic functions of their atomic numbers.
$II$. Non-metallic elements are less in number than the metallic elements.
$III$. The first ionisation energies of elements along a period do not vary in a regular manner.
$IV$. The ground state electronic configuration of $Pd (Z=46)$ is $[Kr] 4d^8 5s^2$.
