(a) Draw a two dimensional representation of the (101) plane for the unit cell of silver. Clearly show the atoms that intersect the plane by drawing circles that are properly scaled. What is the planar density, in terms of: (i) a fraction (ii) atoms $$/{\mathrm{cm}}^2$$ (The atomic radius of silver is $$165\mathrm{pm}$$.) (b) Draw an arrow in a neat cube that represents the $$[2\overline{1}1]$$ direction. If the cube represents the unit cell of silver (see part (a)), calculate its linear density, in terms of: (i) a fraction (ii) atoms $$/\mathrm{cm}$$
