Current Question (ID: 7648)

Question:

$\text{The ionic radius indicates the distance between the nucleus and:}$

Options:

1. $\text{Outermost shell of an atom.}$
2. $\text{Outermost shell of an ion.}$ (Correct)
3. $\text{Outermost shell of the cation only.}$
4. $\text{Outermost shell of the anion only.}$

Solution:

$\text{Hint: Ions can be cation as well as an anion.}$ $\text{Explanation:}$ $\text{Ionic radius means the radius of an ion (cation or anion). The ionic radii can be calculated by measuring the distances between the cations and anions in ionic crystals.}$ $\text{The radius of the ion depends on the effective nuclear charge, more the charge, more heavily the electrons are attracted towards the center and lesser in the size. Hence the ionic radii are inversely proportional to effective nuclear charge.}$
