The two kinds of solids are amorphous and _____________.

Responses
A morphousmorphous
B crystalline

The correct response is B) crystalline.

To answer this question, you need to understand the two main types of solids. Here's how you can determine the answer:

1. Start by understanding what the term "amorphous" means in the context of solids. Amorphous solids lack a regular, repeating arrangement of particles. This means that their atoms or molecules are randomly arranged without any long-range order.

2. Next, think about what the possible alternative to amorphous solids might be. If amorphous solids have no regular arrangement, what kind of solids have a highly ordered and repeating structure?

3. The term "crystalline" describes solids that have a specific, ordered arrangement of particles. In crystalline solids, the atoms or molecules are arranged in a repeated pattern, forming a crystal lattice. This regular arrangement gives crystalline solids distinctive properties such as well-defined angles and faces.

Now that you have a clear understanding of both types of solids, you can determine the answer: B) crystalline.

B crystalline
