(A) The structure of $Na_2S_4O_6$ is shown below:$Na^+O^--S(=O)_2-S-S-S(=O)_2-O^-Na^+$In $Na_2S_4O_6$ (sodium tetrathionate),there are two types of sulphur atoms:$1$. The two terminal sulphur atoms are bonded to three oxygen atoms (two via double bonds and one via a single bond) and one sulphur atom. Their oxidation number is calculated as $+5$.$2$. The two central sulphur atoms are bonded only to two other sulphur atoms. Since the electronegativity of identical atoms is the same,their oxidation number is $0$.The difference in the oxidation numbers of the two types of sulphur atoms is $|5 - 0| = 5$.

Column-$I$	Column-$II$
$A$. Positively charged ion	$1$. $+7$
$B$. Oxidation number of all neutral atoms	$2$. $-1$
$C$. Oxidation number of hydrogen $(H^+)$	$3$. $+1$
$D$. Oxidation number of fluorine in $NaF$	$4$. $0$
$E$. Negatively charged ion	$5$. Cation
	$6$. Anion

The difference in the oxidation numbers of the two types of sulphur atoms in $Na_2S_4O_6$ is
