Helium in its solid form has a crystalline structure and sharp melting point. It is the only element that cannot be solidified using low temperatures at ordinary pressures. It changes to solid form when compressed to a p... More » Science Chemistry States of Matter

Amorphous solids are solids which do not have an crystalline structure. There is no particular order to the make up of these types of solids. When viewed under a microscope or when x-rayed, the molecules that make up the... More » Science Chemistry States of Matter

An amorphous material is one that displays properties of both a solid and a liquid. Mayonnaise is an example of an amorphous substance, since it exhibits liquid properties but the molecules are so arranged that it can wi... More »

A crystalline liquid or solid has a crystal structure composed of a repeating unit cell, which is a particular arrangement of atoms. This repeating unit cell is also called the crystal lattice. More »
