Moseley's law
Moseley’s Law describes the relationship between the frequency of X-rays emitted by elements and their atomic numbers. Discovered by physicist Henry Moseley in 1913, it showed that the energy of the X-rays increases with the atomic number of an element. This finding refined the periodic table, confirming that an element's position is determined by its atomic number rather than atomic mass. Moseley’s Law advanced the understanding of atomic structure and helped identify the properties of elements, playing a crucial role in modern chemistry and physics.

Moseley's Law relates to the X-ray spectra of elements and establishes a relationship between the wavelength of X-rays emitted by an element and its atomic number. Discovered by physicist Henry Moseley in 1913, it shows that as the atomic number increases, the frequency of the emitted X-rays also increases. This helped refine the periodic table, confirming that an element's properties are closely connected to its atomic number rather than its atomic mass, leading to a better understanding of atomic structure and electron configurations. Moseley’s work ultimately contributed to the modern understanding of elements and their organization.
