An amorphous material: Group of answer choices is composed of a collection of many small crystals. lacks systematic and regular arrangement of atoms over relatively large atomic distances. is the perfect and periodic arrangement of atoms within a material. composed of regions of a material where the periodic and repeated arrangement of atoms extends throughout the entirety of the region but not the whole specimen.

lacks systematic and regular arrangement of atoms over relatively large atomic distances

Explanation:

The major difference between a crystalline substance and an amorphous substance is the arrangement of particles.

In a crystalline material, particles are arranged in a definite and regular repeating manner throughout the solid. This definite pattern of particle arrangement accounts for the unique properties of crystalline substances.

On the other hand, amorphous substances lack this regular arrangement hence their properties differ significantly from those of crystalline substances.

the millers tale is the answer.
