What is the differences between amorphous and crystalline solids?

Answer 1

A crystalline solid is one where the molecules are arranged in a regular repeating pattern, leading to a rigid and stable structure. An example is diamonds or table salt. An amorphous solid have a shape that may change over time. An example is glass in a window.

Answer 2

Amorphous solids have a random arrangement of atoms or molecules, resulting in no long-range order, while crystalline solids have a well-defined and repeating three-dimensional arrangement of atoms or molecules. Crystalline solids have a sharp melting point and distinct cleavage planes, while amorphous solids soften over a range of temperatures and do not have cleavage planes.

Answer 3

Degree of hardness
