Moseley a brilliant student of Rutherford, in 1913 made the first detailed study of the characteristic x-ray spectrum emitted by different elements and showed that the square root of the frequency (automic structure) of a spectral line is directly related with the nuclear charge (Z), if the excitation potential is fixed.
When a graph was plotted between root of the frequency × 10–8 and the atomic number (Z), a straight line was obtained.
The results obtained led to the suggestion that (root of the frequency) must be directly proportional to the atomic number of an element.

automic structureµ Z

To give accurate results, Mosley modified this equation as

root of the frequencyµ (Zb)

where b is a constant and is known as screening constant. For Ka and Kb lines, b = 1.

Hence, automic-structure = a(Z – 1).....(1)

where a is proportionality constant.
