Point out the wrong statement: On moving horizontally from left to right across a period in the periodic table

Given below are two statements:
Statement $I$ : The correct order of first ionization enthalpy values of $Li, Na, F$ and $Cl$ is $Na < Li < Cl < F$.
Statement $II$ : The correct order of negative electron gain enthalpy values of $Li, Na, F$ and $Cl$ is $Na < Li < F < Cl$.
In the light of the above statements,choose the correct answer from the options given below :

Fill in the blanks:
$(i)$ Atoms and ions having the same number of electrons are known as ........... .
$(ii)$ The quantitative measure of the tendency of an element to lose an electron is called ........... .
$(iii)$ The screening effect is also known by the name ........... .
$(iv)$ The enthalpy change when a gaseous neutral atom forms a negative ion is called ........... .

Which of the following orders is $NOT$ correct with respect to the mentioned properties?

Match the properties of elements given in List-$I$ with List-$II$.

List-$I$	List-$II$
$(1)$ Active non-metal with high electron gain enthalpy.	$(A)$ $Na$
$(2)$ Soft metal with low ionization enthalpy.	$(B)$ $Sb$
$(3)$ Metalloid that forms ${M_2}{O_3}$ type oxide.	$(C)$ $He$
$(4)$ Chemically inert gas.	$(D)$ $Cl$

Which has maximum $EA$,$EN$ and $IP$ respectively $:-$
$A = 1s^2 \ 2s^2 \ 2p^6$
$B = 1s^2 \ 2s^2 \ 2p^6 \ 3s^2 \ 3p^5$
$C = 1s^2 \ 2s^2 \ 2p^5$
$D = 1s^2 \ 2s^2 \ 2p^6 \ 3s^1$
