Which of the following describes amorphous solids?

Amorphous solids are characterized by their disorganized structure, lacking the regular and orderly arrangement of atoms or molecules that define crystalline solids. This irregularity means that in an amorphous solid, the arrangement of particles is more random and can lead to varying properties, such as different thermal and optical behaviors compared to crystalline structures. The absence of long-range order in amorphous solids is what fundamentally distinguishes them from crystalline solids, which exhibit defined melting points and precise geometric shapes. This inherent disorganization also means that amorphous solids do not have a fixed routine of atomic movement, contributing to their unique characteristics in comparison to more structured materials.
