Density of simple cubic unit cell
WebA simple cubic lattice unit cell contains one-eighth of an atom at each of its eight corners, so it contains one atom total. Calculation of Atomic Radius and Density for Metals, Part … WebJun 4, 2024 · Simple Cubic: 8 corner atoms × ⅛ = 1 atom/cell. The packing in this structure is not efficient (52%) and so this structure type is very rare for metals. Body Centered Cubic, bcc: (8 corner atoms × ⅛) + (1 center atom × 1)= 2 atoms/cell. The packing is more efficient (68%) and the structure is a common one for alkali metals and early ...
