The formation of atoms into a definite pattern is called Space lattice. Which of the following is true?

• A. Space lattice
• B. Crystal lattice
• C. Unit cell
• D. Bravais lattice

Answer: (A)

The idea being tested is the idea of a repeating, ordered arrangement of points in space that defines where atoms can sit in a crystal. That orderly, periodic framework is the space lattice—the infinite grid of lattice points that describes the pattern atoms follow in three-dimensional space. It’s the abstract scaffold that shows how the pattern repeats as you move along different directions. The term space lattice is used to emphasize this spatial, repeating arrangement. A crystal lattice is similar and often used interchangeably, but in this context the phrase space lattice most precisely captures the idea of the repeating lattice points in space. The unit cell is just the smallest repeating block that builds the whole lattice, not the whole pattern itself. A Bravais lattice is one particular classification of such lattices, of which there are 14 in three dimensions.
