Given a hexagonal close packed crystal structure (depicted below) calculate the height of the hexagonal prism, c, in terms of R and a. Recall: APF = volume of atoms in unit cell/volume of unit cell Area of Hexagon = 3 squareroot 3/2 a^2 Volume of prism area of base * c a=2R Chromium forms a hexagonal close packed crystal structure. Determine the theoretical density of chromium rho = nA/V_cN_a

Answer:

Given a hexagonal bar packed crystal edifice (depicted beneath) compute the apex of the hexagonal prism, c, in stipulations of R and a. Recall: APF = capacity of atoms in ace cell/capacity of ace cell Area of Hexagon = 3 squareroot 3/2 a^2 Capacity of prism area of corrupt * c a=2R Chromium forms a hexagonal bar packed crystal edifice. Determine the hypothetical shortsightedness of chromium rho = nA/V_cN_a
