Detailed explanation-1: -An amorphous structure has no organization (not a crystalline structure), and the atomic structure resembles that of a liquid. Commonly, amorphous materials mentioned in the Materials Science Engineering field are amorphous soilds unless otherwise clarified otherwise.
Detailed explanation-2: -Amorphous solid resemble liquids in that they do not have an ordered structure, an orderly arrangement of atoms or ions in a three-dimensional structure. These solids do not have a sharp melting point and the solid to liquid transformation occurs over a range of temperatures.
Detailed explanation-3: -Amorphous solids have two characteristic properties. When cleaved or broken, they produce fragments with irregular, often curved surfaces; and they have poorly defined patterns when exposed to x-rays because their components are not arranged in a regular array. An amorphous, translucent solid is called a glass.
Detailed explanation-4: -There is no orderly arrangement of particles in amorphous solids.
