Multiple Choice
X-ray diffraction measurements on a newly discovered crystalline form of Eu revealed that Eu crystallizes in a body-centered cubic lattice in which the unit cell edge length is 458.3 picometers. Calculate the atomic radius of the Eu atoms in this crystal, based on the assumption that the atoms are tightly packed in the unit cell.Hint: Find the length of the cell body diagonal using the Pythagorean theorem.
