Calculate the percent of volume that is actually occupied by spheres in a body-centered cubic lattice of identical spheres You can do this by first relating the radius of a sphere, r, to the length of an edge of a unit cell, l. (Note that the spheres do not touch along an edge but do touch along a diagonal passing through the body-centered sphere.) Then calculate the volume of a unit cell in terms of r. The volume occupied by spheres equals the number of spheres per unit cell times the volume of a sphere (4r3/3).
Calculate the percent of volume that is actually occupied by spheres in a face-centered cubic lattice of identical spheres. You can do this by first relating the radius of a sphere, r, to the length of an edge of a unit cell, l. (Note that the spheres do not touch along an edge but do touch along the diagonal of a face.) Then calculate the volume of a unit cell in terms of r. The volume occupied by spheres equals the number of spheres per unit cell times the volume of a sphere (4r3/3).
MnO has either the NaCI type structure or the CsCI type structure (see Exercise 69). The edge length of the MnO unit cell is 4.47 10-8 cm and the density of MnO is 5.28 g/cm3. a. Does MnO crystallize in the NaCl or the CsCl type structure? b. Assuming that the ionic radius of oxygen is 140. pm, estimate the ionic radius of manganese.
Barium crystallizes in a body-centered cubic unit cell with an edge length of 3.025 (a) What is the atomic radius of barium in this structure? (b) Calculate the density of barium.
On the basis of the description given, classify each of these solids as molecular, metallic, ionic, network, or amorphous, and explain your reasoning. (a) A soft, slippery solid that has no definite melting point but decomposes at temperatures above 250 C; the solid does not conduct electricity (b) Violet crystals that melt at 114 C and whose vapor irritates the nose; neither the solid nor the liquid conducts electricity (c) Hard, colorless crystals that melt at 2800 C; the liquid conducts electricity, but the solid does not (d) A hard solid that melts at 3410 C; both the solid and the liquid conduct electricity
