What term describes the arrangement of atoms in pure metals?

• A. Orderly rows and columns
• B. Uniform spheres only
• C. Random clusters
• D. Spiral lattice

Answer: (A)

Metals form a crystal lattice—an organized, repeating pattern of atoms that extends in all directions. Describing this as an orderly, repeating arrangement is a simple way to picture how atoms sit at regular positions relative to one another. The phrase about orderly rows and columns captures that regular, grid-like structure, which is why it’s the best match for pure metals’ arrangement.

The other ideas don’t fit long-range order: imagining only uniform spheres misses the sense of a shared, repeating network; random clusters imply no consistent pattern; a spiral lattice isn’t how metal atoms typically pack in a solid.
