The metal gold crystallizes in a face centered cubic unit cell with one atom per lattice point. when x-rays with λ = 1.436 å are used, the second-order bragg reflection from a set of parallel planes in a(n) gold crystal is observed at an angle θ = 20.62°. if the spacing between these planes corresponds to the unit cell length (d = a), calculate the radius of a(n) gold atom.
