3.4 Mosley Experiment
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 (
) of a spectral line is directly related with the nuclear charge (Z), if the excitation potential is fixed.
When a graph was plotted between × 10–8 and the atomic number (Z), a straight line was obtained.
The results obtained led to the suggestion that () must be directly proportional to the atomic number of an element.
µ Z To give accurate results, Mosley modified this equation as
µ (Z – b)where b is a constant and is known as screening constant. For Ka and Kb lines, b = 1.
Hence,
= a(Z – 1).....(1)where a is proportionality constant.
