The answer is true. Amorphous solids, also known as non-crystalline solid, lacks a long-range order seen in a crystalline solid. Examples are glass. polymers and silicon. Many solids around are in an amorphous form.
Amorphous solid is the designation given to a structure that has no long-range (atomic) spatial ordering, such as regular solids. For a material to be considered as regular solid it must have a defined crystalline structure, which corresponds to a positioning of the atoms that compose it. Amorphous materials have no definite geometric shape, may even have some rigidity like ordinary solids, but their atoms are not in spatial organization (at the microscopic level), in which case amorphous solids have no general order, with individual clusters joined together only. by the forces of Van der Waals.
