The ionic crystal of NaCl has an fcc structure as
shown below with the position of the Cl atom
located at : (0 0 0); (½ ½ 0); ( ½ 0 %) and (0
½) and Na atom is located at : (½ ½½) + fcc
translation.
The following are the physical data of NaCl:
- Ionic radius Na = 0.98 A, Cl ion radius
1.81 A
Atomic mass of Na = 22.99 amu, Atomic
mass of Cl = 35.45 amu
NaCl bulk modulus = 2.40 x 1010 N/m
- Madelung's constant = 1.75
Young's modulus in the direction [100] = 5
x 1010 Nm-2
Debye temperature = 281 K
-
State the structural factors of NaCl, F in
fNa and fCl (f = atomic scattering factor).
Also determine the condition (h k 1) so that
the value of F = 0.
Consider a face centered cubic (fcc) crystal in which one atom is placed at each lattice point. The lattice constant is a = 0.7 \: nma=0.7nm. Calculate the volume density of atoms (i.e. number of atoms per unit volume) in units of cm^{-3}cm−3. Values within 5% error will be considered correct.
The elements A and B crystallize in bcc and fcc structures, respectively. Suppose that (i) the crystals of A
and B have the same density, and (ii) the nearest-neighbor distances in these crystals are equal. Calculate the
ratio MA/MB, where MA and MB denote the masses of the A and B atoms, respectively.
