A8.9 Using the Ionic Radius to Calculate Density of Metals
First you need to be able to calculate the length of the cell edge.
Figure 8.5 Calculating. the density of metals
Unless you are talking about a simple cubic lattice, where the cell edge is the diameter or two metal atoms, calculating the density of a metal is tricky. The relationship between the ion radius and the cell edge is shown, but you are unlikely to be asked to work with BCC Or FCC lattices.
