What term describes solid matter with atoms arranged in a regular, repeating pattern?

• A. Crystaline
• B. Crystal Planes
• C. Crystal Shape
• D. Crystal

Answer: (D)

Solid matter with atoms arranged in a regular, repeating pattern is described as a crystal. This orderly arrangement forms a crystal lattice that gives the material long-range order in three dimensions. The noun for the material is “crystal,” while “crystalline” is the adjective used to describe such materials or their properties. The other terms refer to either misspelled form, internal features (crystal planes), or the external shape (crystal shape) rather than the material itself. So, crystal is the best term.
