Worksheet: Atomic Radii from Lattice Parameters
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.
