Question

(a) Draw a picture that represents a crystalline solid at the atomic level. (b) Now draw a picture that represents an amorphous solid at the atomic level.

Short answer

To represent a crystalline solid at the atomic level, draw a square or rectangular grid with regularly spaced atoms at each intersection, and add layers to make it 3-dimensional. Label the diagram as "crystalline solid." For an amorphous solid, draw a group of randomly arranged atoms, add some additional atoms to give a 3-dimensional view, and label the diagram as "amorphous solid." This illustrates the key difference in the arrangement of atoms between crystalline and amorphous solids.

Step-by-step solution

Draw a picture representing a crystalline solid

Crystalline solids have a regular, repeating arrangement of atoms. Common examples include salts, metals, and some minerals. To draw a crystalline solid at the atomic level, do the following: 1. Draw a square or rectangular grid with regularly spaced atoms at each intersection. This grid represents the repeating arrangement of atoms in the crystal lattice. You might consider using different colors for different types of atoms, if necessary. 2. You can also add more layers to the grid to give a 3-dimensional view of the crystal. 3. Label the diagram as "crystalline solid."

Draw a picture representing an amorphous solid

Amorphous solids have a more random arrangement of atoms that do not form any repeating patterns. Examples include glasses, rubber, and some polymers. To draw an amorphous solid at the atomic level, do the following: 1. Draw a group of randomly arranged atoms. The arrangement should not show any regular, repeating pattern like in the crystalline solid. It can be helpful to use different colors for different types of atoms, if necessary. 2. Add some additional atoms above and below the randomly arranged group to give a 3-dimensional view of the amorphous solid. 3. Label the diagram as "amorphous solid." By following these steps, you would have successfully drawn pictures representing a crystalline solid and an amorphous solid at the atomic level. These illustrations will help in understanding the key differences in the arrangement of atoms between these two types of solids.
