    The Model for Polonium Crystal Structure

    Discussion -

    O   O  |  If we cut the cube along a face diagonal, the arrangement of
      O    |  atoms look like the diagram on the left.
    O   O  |     Thus, bd = 4 R
    
  • If the edge of the cube has a length represented by a, and if the radius of the atoms is R, express a as a function of R.

    Hint: \(a = \dfrac{4 R}{\sqrt3}\)

    Discussion -
    a = 4 R / √3
