Q. The correct order of size of iodine species is
A) $I > I^{-} > I^{+}$
B) $I^{-} > I > I^{+}$
C) $I^{+} > I > I^{-}$
D) $I^{-} > I^{+} > I$
Explanation
(b)
The size of an anion is larger than its corresponding neutral atom and the size of cation is smaller than its corresponding neutral atom. Hence, the order of the size of iodine species is as $I^{-} > I > I^{+}$.
