Chapter 2, Problem 56P

Interpretation Introduction

(a)

Interpretation:

True and false

Ionization energy is the energy required to remove the most loosely held electron from an atom in the gas phase.

Concept Introduction:

In chemistry, the energy which is needed to eliminate an electron from an isolated molecule or atom is known as ionization energy which is also known as ionization potential.

Interpretation Introduction

(b)

Interpretation:

When an atom loses an electron, it becomes a positively charged ion.

Concept Introduction:

Atoms contain same number of protons and electrons and they are neutral in nature. An electrically charged particle that is ion produced by either adding electrons to a neutral atom results a negative ion or removing electrons from a neutral atom results a positive ion.

Interpretation Introduction

(c)

Interpretation:

Ionization energy is a periodic property because ground state electron configuration is a periodic property.

Concept Introduction:

The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.

Interpretation Introduction

(d)

Interpretation:

Ionization energy generally increases going from left to right across a period of the periodic table.

Concept Introduction:

The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.

Interpretation Introduction

(e)

Interpretation:

Ionization energy generally increases in going from top to bottom within a column in the periodic table.

Concept Introduction:

The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.

Interpretation Introduction

(f)

Interpretation:

The sign of ionization energy is always positive, the process is always endothermic.

Concept Introduction:

The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.
