Crystal structure represents the manner in which atoms or ions are arrayed in space.
It is defined in terms of the unit celI (1) and the atom (2) within the unit cell.
(1) = direction, (2) = sizes.
(1) = plane, (2) = positions.
(1) = geometry, (2) = positions.
(1) = geometry, (2) = sizes.
For the shown crystal structure, write down (a) the
Bravais lattice and (b) the basis of the primitive unit
cell. For this structure a=b= c and a=B=y%3D90°.
The green (A) atoms at the vertices; blue (B) atom at
the center, pink (C) atoms are the centers of two
opposite faces; and brown (D) atoms at the centers
of four edges of the unit cell.
Note that the a, b and c translation vectors are along
the positive x, y and z axes, respectively, as
shown.
COD
(b) Using the Crystallographer's
formula to determine the density (in g/cm³) of Po:
ρ = Σ Ζ * Μ
Vell* N
You must know that a primitive cubic cell has Z = 1
Since Po is a metal, the value of "i" = 1, since it's the only entity!
MM of Po= 208.998 g/mol
Vcell (in cm³) = a³
Vcell (3.36 x 10-8 cm)³ = 3.793 x 10-23 cm³
N = 6.022 x 1023 atoms/mol
Thus: p = (1 atom/cell) (208.998 g/mol) = 9.16 g/cm³
(3.793 x 10-23 cm³) (6.022 x 1023)
