Describe the crystal structure of iron, which crystallizes with two equivalent metal atoms in a cubic unit cell.
The structure of this low-temperature form of iron (below 910 °C) is body-centered cubic. There is one-eighth atom at each of the eight corners of the cube and one atom in the center of the cube.
Describe the crystal structure of Pt, which crystallizes with four equivalent metal atoms in a cubic unit cell.
This structure of platinum is a face-centered cubic. There is one-eighth atom at each of the eight corners of the cube and one-half atom on each of the six faces of the cube.
What is the coordination number of a chromium atom in the body-centered cubic structure of chromium?
What is the coordination number of an aluminum atom in the face-centered cubic structure of aluminum?
