Quantum Mechanics The term quantum mechanics refers to energy levels and the … Web15 de nov. de 2024 · Bohr model is a modification of the Rutherford model. This model was proposed based on the line spectra of the hydrogen atom. This model proposed that electrons are always traveling in specific shells or orbits around the nucleus. Bohr model also indicated that these shells have different energies and are spherical in shape.

WebWith A. Sommerfeld’s extension of the Bohr theory in 1915–1916, it was turned into a powerful tool of atomic research and adopted and further developed by German physicists in particular. The new and more general Bohr–Sommerfeld theory described the atom in terms of two quantum numbers, while Bohr had originally used only one quantum number. WebWith his model, Bohr explained how electrons could jump from one orbit to another only by emitting or absorbing energy in fixed quanta. For example, if an electron jumps one orbit closer to the nucleus, it must emit energy …
