Calculate the lattice constant, face diagonal, body diagonal and packing density of body centered cubic (BCC) crystal unit cell.
Define lattice and coordination number of a crystal. Obtain the packing density, body diagonal, face diagonal and other lattice parameters of a FCC crystal structure with a clear diagram.
Copper has FCC structure unit cell, atomic mass = 63.55 gm/mol and radius (R) = 0.13 nm. Calculate (i) Packing density (ii) Density of copper (iii) Atomic concentration (iv) Fermi energy.
