Unit Cell Formula: Ca How many carbon atoms occur per unit cell for the diamond crystal sty fucture (shown above)? Fill in each of the LETTERED blanks with the correct number corresponding to the letter positions it the analysis table. (Notice. This question is asking for the number of each type of atom position AFTER multiplying by the fractional value for A through D. The atoms in the interior of the lattice are contained in a shaded region corresponding to the hole geometry of the interior atom) (do not spell answers, express answers numerically. Enter a O if none present, do NOr leave blan) A= B= c= D= What is the Unit Cell Formula for diamond? Co
