We’re being asked to find the atomic radius of crystalline molybdenum (Mo) that has a body-centered (BCC) cubic unit cell.
A body-centered cubic (BCC) unit cell is composed of a cube with one atom at each of its corners and one atom at the center of the cube.
Recall that the edge length (a) of a BCC unit cell can be calculated using the equation:
One of the most important enzymes in the world—nitrogenase, the plant protein that catalyzes nitrogen fixation—contains active clusters of iron, sulfur, and molybdenum atoms. Crystalline molybdenum (Mo) has a body-centered cubic unit cell (d of Mo = 10.28 g/cm3). Calculate the atomic radius of Mo.
