How many atoms of aluminum are present in each unit cell? The answer is six. This means that there are three octahedral and three tetrahedral sites for the Al atom. There is one such site at the center, four on the corners, and one at each of the eight vertices. Bullet Point: This means that there are three octahedral and three tetrahedral sites for the Al atom. There is one such site at the center, four on the corners, and one at each of the eight vertices. The answer is six. This means that there are three octahedral and three tetrahedral sites for the Al atom. There is one such site at the center, four on the corners, and one at each of the eight vertices. Octahedron faces have adjacent edges with lengths equal to 0.5056 Angstroms (Aluminum has a radius of 0.1477 A). Tetrahedron Faces also have adjacent edge lengths equal to 0 centimetres
