Rank of the unit cell : rank of a cell is the number of atoms a substance contains in its unit cell
for example : if the cell has bcc structure its rank wud be= 1/8 * 8 + 1=2
similarly fcc wud hav rank=4
remeber rank of o unit cell is different from coordination number which is the number of nearest neighbors of a point in a space lattice, of an atom or an ion in a solid, or of an anion or cation in a solution
