Amorphous materials are?

Have sharp melting points

Undergo clean cleavage when cut with knife

Have perfect arrangements of atoms

Can presses small regions of orderly arrangements of atoms

Amorphous solids: Unlike crystalline solids, which have a regular,

An ordered arrangement of atoms throughout their structure,

Amorphous solids lack this long-range order.

However, within small regions of the material,

There can be some degree of local order.
