Question

Give two important points of Moseley’s work on X-rays

Answer 1

Moseley discovered a systematic mathematical relationship between the wavelengths of the X-rays produced and the atomic numbers of the metals that were used as the targets in X-ray tubes. This has become known as Moseley's law.

Answer 2

Explanation:

Moseley's law emphasizes on the atoms emitting the characteristic x-rays. It states that the atomic number is proportional to the square root of the frequency of the emitted x-ray.

Not only was the atomic number created as a measurable experimental amount, but it also gave it a physical significance as a positive charge on the nuclear nucleus.

Moseley's experiments in X-ray spectroscopy also showed that both cobalt and nickel have the atomic numbers as 27 and 28, and are placed in the periodic table.
