MODULE 4: Structure of Crystalline and Amorphous Solids

Question 1

What solids does not have a well-defined geometric pattern?

Answer 1

Amorphous Solids

Question 2

What is the basic repeating structural unit of crystalline solids?

Answer 2

unit cell

Question 3

What is an amorphous solid that can convert sunlight into electrical energy?

Answer 3

rubber

Question 4

Why are the crystalline solids considered as true solids?

Answer 4

because of its sharp melting point, that once it reaches its meltping point it will dissolve immediately.

Question 5

Why are the solid-state and molten state of ionic crystals considered poor
electrical conductors?

Answer 5

particles are not held firmly.

Question 6

has the strongest intermolecular forces and ionic crystal?

Answer 6

salt

Question 7

has covalent crystals with a very high melting point?

Answer 7

quartz

Question 8

is an amorphous solid with no sharp melting points?

Answer 8

rubber

Question 9

They are composed of a huge number of small crystals with a definite
geometrical shape making them rigid and incompressible

Answer 9

Crystalline solids
