An element of atomic weight $40$ has $2, 8, 8, 2$ as the electronic configuration. Which one of the following statements regarding this element is not correct?

Given below are two statements :
Statement $I$ : $K > Mg > Al > B$ is the correct order in terms of metallic character.
Statement $II$ : Atomic radius is always greater than the ionic radius for any element.
In the light of the above statements,choose the correct answer from the options given below

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

Match the Column $I$ with Column $II$ and select the correct answer using the given codes.

Column $I$ (Element types)	Column $II$ (Electronic configuration)
$A$. Inert-gas elements	$1. (n-1)d^{1-10} ns^{1-2}$
$B$. Transition elements	$2. ns^2 np^6$
$C$. Inner-transition elements	$3. (n-2)f^{1-14} (n-1)s^2 p^6 d^{0-1} ns^2$

Which of the following statements are true?
$A.$ Unlike $Ga$ that has a very high melting point,$Cs$ has a very low melting point.
$B.$ On Pauling scale,the electronegativity values of $N$ and $Cl$ are not the same.
$C.$ $Ar$,$K^{+}$,$Cl^{-}$,$Ca^{2+}$,and $S^{2-}$ are all isoelectronic species.
$D.$ The correct order of the first ionization enthalpies of $Na$,$Mg$,$Al$,and $Si$ is $Si > Al > Mg > Na$.
$E.$ The atomic radius of $Cs$ is greater than that of $Li$ and $Rb$.
Choose the correct answer from the options given below

To which group and period does the element belong if the electronic configuration of an element in its $-2$ oxidation state is $1s^2 2s^2 2p^6 3s^2 3p^6$?
