- Calculate the unit cell edge length of copper metal, which has an fcc arrangement. The radius of a copper atom is 126 pm.arrow_forwardThe radius of gold is 144 pm, and the density is 19.32 g/cm3. Does elemental gold have a face-centered cubic structure or a body-centered cubic structure?arrow_forwardVanadium metal has a density of 6.11 g/cm3. Assuming the vanadium atomic radius is 132 pm, is the vanadium unit cell primitive cubic, body-centered cubic, or face-centered cubic?arrow_forward
- Tungsten crystallizes in a body-centered cubic unit cell with an edge length of 3.165 . (a) What is the atomic radius of tungsten in this structure? (b) Calculate the density of tungsten.arrow_forwardThe density of polonium metal is 9.2 g/cm3. If the extended lattice of polonium exhibits a simple cubic unit cell, estimate the atomic radius of polonium.arrow_forward1. The unit cell of silicon carbide. SiC is illustrated in the margin. In what type of unit cell are the (dark gray) C atoms arranged? primitive cubic body-centered cubic face-centered cubicarrow_forward
- The density of copper metal is 8.95 g/cm3. If the radius of a copper atom is 127.8 pm, is the copper unit cell primitive, body-centered cubic, or face-centered cubic?arrow_forward8.98 If you know the density of material and the length of the edge of its cubic Iattice, how would you determine if it is face-centered cubic, body-centered cubic, or simple cubic Would you have to look up any information?arrow_forward(a) Determining an Atom Radius from Lattice Dimensions: Gold has a face-centered unit cell, and its density is 19.32 g/cm3. Calculate the radius of a gold atom. (b) The Structure of Solid Iron: Iron has a density of 7.8740 g/cm3, and the radius of an iron atom is 126 pm. Verify that solid iron has a body-centered cubic unit cell. (Be sure to note that the atoms in a body-centered cubic unit cell touch along the diagonal across the cell. They do not touch along the edges of the cell.) (Hint: The diagonal distance across the unit cell = edge 3.)arrow_forward
