Question

The approximate percentage of vacant space in a Silicon cubic cell having crystal structure similar to diamond

Answer: 0066

💡 Solution & Explanation

Silicon crystallizes in a diamond cubic structure. The packing efficiency of the diamond cubic structure is approximately 34%. Therefore, the percentage of vacant (empty) space is $100\% - 34\% = 66\%$. Therefore, correct answer is 0066.
