The radius of carbon atom is — Solid State Chemistry Question

💡 Solution & Explanation

In diamond, 8 carbon atoms are present per unit cell. Density of diamond = 3.6 g/cm3. Using density formula, we find edge length a of diamond is 3.56 A. In diamond structure, r_C = a * sqrt(3) / 8 = 3.56 * 1.732 / 8 = 0.77 A \u2248 0.76 A.
