Question:

Correct order of the size of iodine species is

Updated On: Jul 28, 2022

$I > I^- > I^+$
$I > I^+ > I^-$
$I^+ > I^- > I$
$I^+ > I > I^+$

Hide Solution

Verified By Collegedunia

The Correct Option is D

Solution and Explanation

Size of anion is more than the neutral atom and size of cation is less than the neutral atom. As such correct order is :

I^+ > I > I^+

P-Block Elements

P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.

P block elements consist of:

Group 13 Elements: Boron family
Group 14 Elements: Carbon family
Group 15 Elements: Nitrogen family
Group 16 Elements: Oxygen family
Group 17 Elements: Fluorine family
Group 18 Elements: Neon family
