Nature of Solids

This type of solid forms a regular repeating

three-dimensional structure called a crystal lattice. What type of solid is this?

• amorphous

• crystalline

• glass

• diamond

In amorphous solids, the atoms or molecules are held together in a completely random formation.

• true

• false

Which of the following is not true about crystalline solids?

• Have a sharp melting point

• Crystalline solids are anisotropic in nature

• Cannot be cleaved along a definite plane

• They are considered as true solids

Which of the following is true of solids?

• Solids maintain a defined shape and size under all conditions.

• All solids have a crystalline structure.

• All solids maintain a defined shape and size if conditions remain constant.

• All solids have a lattice structure at the atomic level.

One major difference between crystalline and amorphous solids is that

• crystalline solids have a precise melting point.

• amorphous solids have a lattice structure.

• amorphous solids always behave consistently and uniformly.

• crystalline solids break unpredictably and can produce curved fragments.

Solids have many different properties. ___________ solids are known for their ability to be flattened into a sheet, stretched into a wire, and to conduct energy well.

• Molecular

• Metallic

• Covalent Network

• Ionic

It is possible to tell the difference between a solid with a crystalline structure and one with an amorphous structure just by looking at it.

• True

• False

Which statement is true about the properties of solids?

• Metallic solids have a high melting point.

• Network solids are generally not soluble in water.

• Molecular solids do not dissolve easily in water.

• All ionic solids are similar in density.

• Glass structure

• Crystalline structure

• Quartz crystalline structure

• Silicon dioxide rings
