Chapter 2, Problem 5MCP

(a)

Interpretation Introduction

Interpretation:

Among Bromine and Chlorine which one is larger has to be given.

(b)

Interpretation Introduction

Interpretation:

Among Bromine and Chlorine which one has larger ionization energy has to be compared.

Concept Introduction:

Ionization energy is the minimum energy that is required to remove one electron from the valence shell of a gaseous atom.

Ionization energy increases moving from left to right across a period.

(c)

Interpretation Introduction

Interpretation:

Among Bromine and Chlorine which one has larger electron affinity has to be given.

Concept Introduction:

Electron affinity is the ability to accept an electron.  In periodic table, Electron affinity decreases from top to bottom in a group.

(d)

Interpretation Introduction

Interpretation:

The electronic configuration of Chlorine has to be written.

(e)

Interpretation Introduction

Interpretation:

The electronic configuration of Bromine has to be written.

(f)

Interpretation Introduction

Interpretation:

The charges of the ions formed from Chlorine and Bromine has to be provided.

Concept Introduction:

Anions are electrically negative charged particles that result from a gain of one or more electrons by the neutral atom.

  $\text{X}\stackrel{{\text{+e}}^{\text{-}}}{\to }{\text{X}}^{-}$

(g)

Interpretation Introduction

Interpretation:

The electronic configurations of the ${\text{Cl}}^{\text{-}}\text{and}{\text{Br}}^{\text{-}}$ ions has to be provided.
