Q) Diamond has ZnS type Edge length 100 pm Calculate bond length of
CC bond and effective number of carbon atoms in one unit cell

Raveena Sharma · Accepted Answer

The solution is as follows:

ZnS has FCC lattice Thus,

4r =
2a r = a22=35 pmAnd thus, bond length 2r = 2×35 = 70 pmNumber of atoms in FCC = 18×8+12×6 = 4

Q). Diamond has ZnS type. Edge length 100 pm. Calculate bond length of CC bond and effective number of carbon atoms in one unit cell.
