The Space Lattice and Unit Cells

Every matter consists of atoms, molecules, and ions. If these atoms, molecules, and ions (micro-particles) are represented in a three-dimensional space-occupying certain specific points in space, then these arrangements are termed as space lattices and the specific points which are being occupied by atoms, molecules and ions are termed as lattice points. The atoms, molecules, and ions at the lattice points are generally grouped in a regular fashion and repeat periodically at the three-dimensional space.

Question

a) Draw the [11 0], [-1 1 0], [ 0-1-1] directions for FCC
and prove they are crystallographically equivalent.
The family of directions is shown with <> these
brackets. So we can say these directions are part of
the < 11 0> family of directions.
b) Draw the (1 o 0), (-1 0 0), (0 -1 0), and (00-1) planes
for FCC and prove they are crystallographically
equivalent. The family of directions is shown with {}
these brackets. So we can say these planes are part
of the {10 0} family of planes.

3 Copper Unit Cell Uniqueness Here's a weird way to describe the structure of copper: Cu falls into the tetragonal crystal system with a = 0.256 nm, c = 0.362 nm = a√√2, and atoms located at 000 and. Its density is 8.94 g/cc at room temperature. (a) Draw a few adjacent units cells of the structure as described in this "weird" way. You should be able to see that there is a much more convenient way to describe the structure. What is it? (The point I wish to make is that there are many different unit cells that can be used to describe any given crystal, so we usually choose the one that is easiest to visualize.) (b) Calculate the radius of a copper atom using the above information. (c) Calculate the lattice parameter of the "better" unit cell of Cu.
