In this worksheet, we will practice calculating the radii of atoms or ions in a crystal from the lattice parameters and Bravais lattice type.
X-rays of wavelength 0.1435 nm are
diffracted by a cubic metal lattice, producing a second-order () reflection
at . The
metal has a density of 19.3 g/cm3
and molar mass of 197 g/mol. Calculate
the radius of the metal atom.
