What are crystalline and amorphous two categories of?

Answer 1

These are two out of three categories of solids according to their geometry and arrangement. Crystalline solids have proper geometry having the particle arranged on definite axes possessing sharp melting point such as common salt, diamond, etc. Whereas amorphous solids neither have ordered arrangement nor a definite geometry. They have long range melting point such as glass, plastic, etc.

Answer 2

Crystalline and amorphous are two categories of solid materials based on their atomic arrangement. Crystalline solids have a well-defined, orderly arrangement of atoms with a repeating pattern, while amorphous solids have a random or disordered atomic structure. This difference in atomic arrangement affects properties such as transparency, hardness, and melting point.

Answer 3

I think your trying to ask what are the two types of solids, Crystalline and blank. Crystalline and Amorphous are the two types of solids. Hope it helped!

Answer 4

Crystalline and amorphous are two categories of solids. A crystalline solid has a highly regular shape, the opposite is true for an amorphous solid.
