The unit cell of a diamond structure is best described as which of the following? (2020)

Step 1: Understand what a unit cell is. A unit cell is the smallest repeating unit in a crystal structure.
Step 2: Learn about the diamond structure. The diamond structure is a specific arrangement of atoms in a crystal.
Step 3: Identify the type of lattice in the diamond structure. The diamond structure is based on a face-centered cubic (FCC) lattice.
Step 4: Recognize that the diamond structure has a basis. A basis is a group of atoms associated with each lattice point.
Step 5: Note that in the diamond structure, the basis consists of two carbon atoms.
Step 6: Combine the information: The diamond structure is a face-centered cubic lattice with a basis of two carbon atoms.

Diamond Structure – The diamond structure is a crystalline arrangement of carbon atoms that can be described as a face-centered cubic (FCC) lattice with a basis of two carbon atoms.
Face-Centered Cubic (FCC) Lattice – A type of crystal structure where atoms are located at each of the corners and the centers of all the cube faces.
Basis of a Unit Cell – The specific arrangement of atoms associated with each lattice point in a crystal structure.
