Flashcards

Crystalline Solid Arrangement

Atoms, molecules, or ions are arranged in a highly ordered microscopic structure, forming a crystal lattice.

Fixed Melting Point

Crystalline solids have a sharp, well-defined temperature at which they transition from solid to liquid.

Isotropic Properties

Having the same properties in all directions.

Polymorphism

The ability of a solid material to exist in more than one crystal structure.
