The Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy (hν).

Learn how Bohr’s model of the hydrogen atom explained the radiation spectrum of atomic hydrogen based on the quantum theory. Review the historical discoveries of the atomic structure and the emission and absorption spectra of elements.
Explore different models of the hydrogen atom, such as Bohr, quantum mechanics and wave-particle duality, by shooting light at the atom. Compare the predictions and experimental results of each model and learn how scientists figured out the structure of atoms.
Learn how Bohr’s model explained the radiation spectrum of atomic hydrogen based on the postulates of quantum theory. Explore the history and experiments that led to the discovery of the atomic nucleus and the Balmer series of hydrogen emission lines.
23 Οκτ 2024 · The Bohr model of the atom, proposed by Niels Bohr in 1913, explained the spectral lines of hydrogen and other atoms using quantum theory. It postulated that electrons orbit the nucleus in discrete orbits and emit or absorb energy when they jump between them.
Learn how Bohr explained the atomic spectrum and size of hydrogen using the planetary model of the atom and quantized energy levels. Explore the triumphs and limits of Bohr’s theory and its applications to other elements.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral hydrogen atom contains a nucleus of a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1]
