Chapter 12, Problem 79E

Interpretation Introduction

(a)

Interpretation:

Uranium, $\text{U}$ 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 atoms of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(b)

Interpretation:

Fluorine, ${\text{F}}_{\text{2}}$ 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 atoms of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(c)

Interpretation:

Uranium hexafluoride, ${\text{UF}}_{\text{6}}$ 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 atoms of two or more elements bonded together by the ionic bonds.

Interpretation Introduction

(d)

Interpretation:

Hydrogen fluoride, $\text{HF}$ 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 atoms of two or more elements bonded together by the ionic bonds.
