Question
Number of carbon atoms per unit cell of diamond is
Answer: C
💡 Solution & Explanation
In the diamond cubic structure, carbon atoms form an FCC lattice (contributing 4 atoms) and occupy alternate tetrahedral voids (contributing another 4 atoms). Total number of carbon atoms per unit cell = 4 + 4 = 8. Therefore, correct answer is C.
