SUMMARY

Moseley's law establishes that the frequency of the K-alpha emission lines of elements is proportional to the square of the atomic number (Z). The formula derived from his experiments is (Z-1)² proportional to the square root of the frequency, accounting for the screening effect with the -1 term. While the Bohr model effectively explains this relationship, the quantum mechanical (QM) interpretation focuses on the probabilistic nature of electron transitions and energy levels, providing a deeper understanding of spectral line frequencies.

PREREQUISITES
  • Understanding of Moseley's law and its significance in atomic physics

  • Investigate the relationship between atomic number and spectral lines
  • Learn about the limitations of the Bohr model in explaining atomic behavior
USEFUL FOR

Physicists, chemistry students, and educators interested in atomic structure and quantum mechanics, particularly those studying the implications of Moseley's law in modern physics.

moseley did experiments on various elements and showed that the frequency of the k-alpha emission was proportional to the square of the proton no.

The formula is (z-1)^2 proportional to the square root of frequency, with the -1 thrown in for the screening effect.

The bohr model can explain moseleys law quite easily, however how does qm interpret this?

the frequency of the spectral lines, that is.
