Explain: a) The similarity between the electron and the X-ray diffraction patterns of aluminium. b) The line in the hydrogen atom spectrum splits into two when placed in a magnetic field. c) The appearance of coloured lines for H atom in the Balmer series while the Lyman series can only be observed with an ultraviolet lamp.

The first four peaks in the X-ray powder diffraction pattern of sodalite are at 2 values of 9.97°, 14.12°, 17.32° and 20.02°. The radiation used for the experiment was Cu K with  = 1.5418 Å. Determine the lattice type and calculate the length, a, of the cubic unit-cell.

Using powder X-ray diffraction to analyse a metal compound, a simple pattern of peaks resulted, where the largest peak existed at an angle of 2θ= 19.8°. However, when a similar sample was analysed that contained a metallic impurity, this 2θ value became 22.4°. What does this suggest is happening to the crystal lattice and why?

Do you expect to get a different x-ray diffraction pattern for two samples of pure Aluminum:...

Do you expect to get a different x-ray diffraction pattern for two samples of pure Aluminum: Sample #1 – a cube 1cm x 1cm x 1cm in size, or Sample #2 - a powder of aluminum with a particle size diameter of 1 mm?
