Regular, repeating arrangement of atoms in a mineral?

• A. Crystal
• B. Crystal Shape
• C. Crystal Structure
• D. Doubling

Answer: (C)

The regular, repeating arrangement of atoms in a mineral is described by its crystal structure. This refers to how atoms or ions occupy specific positions in a three-dimensional lattice, repeating in all directions to form the internal blueprint of the mineral. That internal order is what gives minerals their symmetry, cleavage, and overall crystalline behavior. The visible external form, or crystal shape, arises from this internal arrangement but is not the arrangement itself. The term doubling has no relevance to describing atomic organization.
