"WebThe excited atom then returns to its ground state with emission of x-rays or Auger electrons. K x-rays are emitted when an outer electron fills a "hole" left in the K shell. In 1913, Moseley published measurements of characteristic energies of K x-rays of many elements, explaining them in terms of the then-new Bohr atomic theory. " - Mosley model of atom

Moseley's law is an empirical law concerning the characteristic x-rays emitted by atoms. The law had been discovered and published by the English physicist Henry Moseley in 1913-1914. Until Moseley's work, "atomic number" was merely an element's place in the periodic table and was not known to be associated with any measurable physical quantity. In brief, the law states that the square … WebBohr's 'solar system' model of the atom is the way that most people think about atoms today.

The electrons revolve round the nucleus only in certain selected circular paths called orbits. 2. Energy of an electron in one of its allowed orbits is fixed. As long as an electron remains in one of its allowed orbit, it can not absorb or radiate energy. 3.
