Crystalline and Amorphous Solids

What is the atomic structure of crystalline solids?

• Regular, repeating pattern of atoms or molecules in a three-dimensional arrangement

• Irregular, non-repeating pattern of atoms in a three-dimensional arrangement

• No specific arrangement of atoms in a one-dimensional pattern

• Random arrangement of atoms in a two-dimensional structure

Name one property of amorphous solids.

• Perfectly symmetrical arrangement

• Easily deformable

• Highly organized structure

• Lack of long-range order

How is the structure of amorphous solids different from crystalline solids?

• Amorphous solids have a highly ordered atomic structure

• Amorphous solids have a perfect crystalline structure

• Amorphous solids have a regular and repeating atomic arrangement

• Amorphous solids have a disordered atomic structure

What are the differences between crystalline and amorphous materials?

• Atomic arrangement, melting point, and mechanical properties

• Transparency, hardness, and thermal expansion

• Boiling point, flexibility, and chemical composition

• Color, density, and electrical conductivity
