Chapter 6, Problem 5STP

Interpretation Introduction

Interpretation:

The sphere which represents ion is to be identified among given.

Concept Introduction :

The electron configuration of an element defines how its electrons are arranged throughout its atomic orbitals. Standard notation is used to represent atomic electron configurations, placing all electron-containing atomic subshells in sequential order. The number of electrons held by the subshell is indicated by superscript.

Answer to Problem 5STP

Sphere B

Explanation of Solution

Anions are formed by gaining electrons. If an atom gains one or more electrons, the nuclear charge remains the same, but the no. of electrons increases. An increase in the number of electrons increases the electrostatic repulsion, which leads to an increase in the size of the atom.

So, the sphere having a larger size represents the anion.

Thus, sphere B represents the anion.
