Which of the following statements about crystalline and amorphous solids is true?
A)A crystalline solid is composed of atoms or molecules arranged with long-range repeating order.
B)An example of a crystalline solid is glass.
C)An example of an amorphous solid is table salt (NaCl).
D)An amorphous solid is composed of atoms or molecules arranged with long-range repeating order.
E)An amorphous solid has the well-ordered geometric arrangements of atoms.

Question

Quizplus · Accepted Answer

Crystalline solids have long-range repeating patterns in the atomic or molecular arrangement, while amorphous solids lack such patterns. Glass is an example of an amorphous solid, and table salt is an example of a crystalline solid with a repeating pattern of sodium and chlorine ions arranged in a lattice. Therefore, options B, C, D and E are false.
