(b) Copper crystallises as FCC (face centred cubic). Given that the atomic radius and density of
a given copper sample are 1.28 x 10-10 m and 8.98 x 10' kg/m' respectively, carry out the following:
(i)
Calculate the mass of the copper sample. Take Avogadro's number, NA = 6.023 x 1023
atoms/mole.
If the interatomic planar spacing, d, in the sample above is 2.96 x 1010 m, determine the angle
at which the first Bragg reflection will occur from the (111) plane if x-radiation of wavelength
1.52 x 10-10 m is used for the analysis.
(ii)
(e) Explain what you understand by the statement: “the bonding in a solid is 30 % ionic and
70 % covalent". Why such types of bondings are occurred in a materials. Give proper
reasoning with examples.
3. Show that in an ideal hexagonal-close-packed (hcp) structure, where the atomic
spheres touch each other, the ratio c/a is given by
:-()*
( 8 \ 1/2
= 1.633.
(The hep structure is discussed in Section 7.)
4 The packing ratio is defined as the fraction of the total volume of the cell that is
filled by atoms. Determine the maximum values of this ratio for equal spheres
located at the points of simple-cubic, body-centered-cubic, and face-centered-cubic
crystals.
