Chapter 12, Problem 80E

Interpretation Introduction

(a)

Interpretation:

Plutonium, $\text{Pu}$ is an atom, a molecule, or a formula unit is to be identified.

Concept introduction:

An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of same or different elements bonded together by a covalent bond. A formula unit is the combination of atom of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(b)

Interpretation:

Oxygen, ${\text{O}}_{\text{2}}$ is an atom, a molecule, or a formula unit is to be identified.

Concept introduction:

An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of the atom of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(c)

Interpretation:

Plutonium(III) oxide, ${\text{Pu}}_{\text{2}}{\text{O}}_{\text{3}}$ is an atom, a molecule, or a formula unit is to be identified.

Concept introduction:

An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of an atom of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(d)

Interpretation:

Hydrogen peroxide, ${\text{H}}_2{\text{O}}_2$ is an atom, a molecule, or a formula unit is to be identified.

Concept introduction:

An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of the atom of two or more elements bonded together by the ionic bonds.
