The miller indices for the shaded plane is 101 213 203 213 F

The miller indices for the shaded plane is (101) (213) (203) (213) For the following 2 problems: The lattice parameter of copper is 0.362 nm. The atomic Weight of copper is 63.54 g/mole. Copper forms an FCC structure. Answer the following questions. Volume of the unit cell of copper in cubic centimeters is 0.047 Times 10^-27 0.047 Times 10^-21 0.13 Times 10^-12 Density of copper in g/cm^3 is 897.9 0.11 8.98 A cube plane has the following axial intercepts: a=1/2, b = 1/3. C = 1. The miller indices of this plane is (132) (326) (231) Metallic bonds are: Directional Non-directional Weaker than Van Der Waals bonds Present in ionic crystals The figure on the right is a(n) vacancy vacancy and interstitial atom edge dislocation screw dislocation Atomic number equals number of protons in the nucleus number of electrons in a cation number of neutrons in the nucleus the number of atoms in a mole of atoms

Solution

15. C. (3 -1 2)

16.    lattice parameter a = 0.362 nm

          volume of unit cell, V = a³ = (0.362)³ = 0.047 nm³ = 0.047x10^-21 cm³

17. density of copper is 8.98 gm/cm³

18. mille indices are (2 3 1)

19. metallic bonds are non directional.

20. the figure on the right is a vacancy.

21. atomic number equals number of protons in the nucleus.
