Question

Size of the iodine species following the order:
A. `I^(+) gt I^(+) gt I`
B. `I gt I^(-) gt I^(+)`
C. `I gt I^(+) gt I^(-)`
D. `I^(-) gt I gt I^(+)`

Answer 1

Correct Answer - D
Due to the addition of an electron to the neutral an anion is formed, and the electron to proton ratio increases, hence the electron cloud in the anion expands, resulting in the increased anion size.
