How to Practise Crystal Lattices and Unit Cells
Start with the number of atoms per unit cell: 1 for simple cubic, 2 for body-centred and 4 for face-centred cubic. Then practise density = Z·M/(a³·Nᴀ) and the relation between edge length and atomic radius in each cubic cell.
Then work through voids and coordination number.
