The ½-monolayer termination (octahedral and tetrahedral Fe) of magnetite (111) underwent slightly more relaxation than the ¼-monolayer termination, with consequently lower surface energy. A calculated STM image for ¼-monolayer magnetite is compared to an observed image at positive bias and suggests that the tetrahedral Fe …

The equation for density is: density = mass / volume. ρ = m/V. The reciprocal of density (V/m) is its specific volume. Density Examples. Density tends to be higher for solids than for liquids, which are in turn more dense than gases. For example, the density of iron is 7.87 g/ml. The density of pure water (a defined value) is 1 gram per ...
