Question
What is the size of the largest atom that could be fit into tetrahedral holes of the lattice without disturbing the lattice?
Answer: A
💡 Solution & Explanation
For FCC, $R = 0.125$ nm. Radius of tetrahedral void $r = 0.225 \times R = 0.225 \times 0.125 = 0.028125 \approx 0.028$ nm. Therefore, correct answer is A.
