(a) Interpretation: Whether the given statement “A high melting solid that conducts electricity is probably a metal” is true or false is to be predicted. In case of false statement, true statement is to be stated. Concept introduction: A metal is considered as a good conductor of heat and electricity in which ions are present. These ions are responsible for the conduction of heat and electricity. Metals are held by very strong forces and form a bond which is known as metallic bond.

Question

Chapter 15, Problem 15.8TC

Interpretation Introduction

(a)

Interpretation:

Whether the given statement “A high melting solid that conducts electricity is probably a metal” is true or false is to be predicted. In case of false statement, true statement is to be stated.

Concept introduction:

A metal is considered as a good conductor of heat and electricity in which ions are present. These ions are responsible for the conduction of heat and electricity. Metals are held by very strong forces and form a bond which is known as metallic bond.

Interpretation Introduction

(b)

Interpretation:

Whether the given statement “Covalent network solids are usually good conductors of electricity” is true or false is to be predicted. In case of false statement true statement is to be stated.

Concept introduction:

Covalent solids are large and continuous structure. Covalent solids have very high melting point and they require very high energy to break the covalent bonds present within the structure. Diamond is one of the covalent solid of carbon atoms.

Interpretation Introduction

(c)

Interpretation:

Whether the statement “A solid that melts at 152o C is probably an ionic crystal” is true or false is to be predicted. In case of false statement true statement is to be stated.

Concept introduction:

Ionic crystals is one of the types of crystalline solids which are made up of positively and negatively charged ions. Both negative and positive ions are responsible for the conduction of electricity in liquid state. Ionic crystals are less conducting is solid state but acts as good conductors when dissolved in water.

Interpretation Introduction

(d)

Interpretation:

Whether the given statement “A soluble molecular crystal is a nonconductor of electricity but a good conductor when dissolved”.is true or false is to be predicted. In case of false statement, true statement is to be stated.

Concept introduction:

Molecular crystals are formed by the weak interactions among the molecules such as molecular structure of iodine molecule. Molecular crystals possess low melting point.

Molecule crystals remain in their molecular form. They are soft and due to their non-polar nature, they are soluble in non-polar solvents.
