estion Four Explain why the average density of metals is higher than that of ceramics or polymers i.e pmetals > (a) Peramics > Ppolymers. (b) Copper crystallises as FCC (face centred cubic). Given that the atomic radius and mass of a given copper sample are 1.28 x 10:10 m and 64.15 g respectively, calculate the density of the copper sample. Take Avogadro's number, NA = 6.023 x 1023 atoms/mole. (c) The linear density, LD, of an atom is given by the equation = Natoms where Natoms is the Ldv number of atoms and Lav is the unit length of the direction vector, both taken on a particular plane. Calculate the linear density of an aluminium atom with a lattice parameter of 4.05 x 1010 m and in a [110] direction. (d) Using neat sketches, show the difference between a triclinic and hexagonal crystal systems.
