Which of the following techniques can be used to determine the volume of a single atom of silicon in an ultrapure crystal of the element?

Question

Quizplus · Accepted Answer

X-ray diffraction is a technique used to determine the atomic and molecular structure of a crystal, by which the crystalline atoms cause a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. This information can be used to determine the positions of the atoms in the crystal as well as their chemical bonds, their disorder, and various other information. Since silicon is a crystalline material, X-ray diffraction is suitable for determining the volume of a single atom within its crystal lattice.
