Which of the following arrangements does not represent the property indicated against it?

Which of the following sets is incorrect?

Observe the following statements:
$I$. The physical and chemical properties of elements are periodic functions of their electronic configuration.
$II$. Electronegativity of fluorine is less than the electronegativity of chlorine.
$III$. Electropositive nature decreases from top to bottom in a group.
The correct answer is:

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 $[Kr] 4d^8 5s^2$.

Diagonal relationship is shown by

Consider the following statements:
$(i) Na_2O < MgO < ZnO < P_4O_6$ - Acidic property
$(ii) F > Cl > Br$ - Electron gain enthalpy
$(iii) M^{2-} > M^{-} > M^{+} > M^{2+}$ - Ionic size
$(iv)$ The second ionisation enthalpy of $Cu$ is more than the second ionisation enthalpy of $K$.
