The given spheres has to be identified as M g 2 + , F − , N a + and S 2 − Concept Introduction: Ionic radius is the distance between the atomic nucleus and outermost electron of an ion. From the ionic radius, the size of ions can be visualized When an atom gets converted to an anion, the charge of nucleus remains the same while the number of electrons increases. This increases the repulsion and hence the electron cloud enlarges which results in the increase in ionic radius. When an atom gets converted to a cation, the charge of nucleus remains the same while the number of electrons decreases. This decreases the repulsion and hence the electron cloud reduces which results in the decrease in ionic radius.

Answer 1

Question

Chapter 8.3, Problem 2RC

Interpretation Introduction

Interpretation: The given spheres has to be identified as Mg2+, F−, Na+ and S2−

Concept Introduction:

Ionic radius is the distance between the atomic nucleus and outermost electron of an ion. From the ionic radius, the size of ions can be visualized

When an atom gets converted to an anion, the charge of nucleus remains the same while the number of electrons increases. This increases the repulsion and hence the electron cloud enlarges which results in the increase in ionic radius.

When an atom gets converted to a cation, the charge of nucleus remains the same while the number of electrons decreases. This decreases the repulsion and hence the electron cloud reduces which results in the decrease in ionic radius.
