  2. Hydrogen atom - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_atom

    For hydrogen-1, hydrogen-2 , and hydrogen-3 which have finite mass, the constant must be slightly modified to use the reduced mass of the system, rather than simply the mass of the electron. This includes the kinetic energy of the nucleus in the problem, because the total (electron plus nuclear) kinetic energy is equivalent to the kinetic ...

  3. Hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen

    The ground state energy level of the electron in a hydrogen atom is −13.6 eV, [24] equivalent to an ultraviolet photon of roughly 91 nm wavelength. [25] The energy levels of hydrogen are referred to by consecutive quantum numbers , with n = 1 {\displaystyle n=1} being the ground state.

  4. Hydrogen spectral series - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_spectral_series

    n′ (often written ) is the principal quantum number of the lower energy level, n (or ) is the principal quantum number of the upper energy level, and; is the Rydberg constant. (1.096 77 × 10 7 m −1 for hydrogen and 1.097 37 × 10 7 m −1 for heavy metals). [5] [6]

  6. Degenerate energy levels - Wikipedia

    en.wikipedia.org/wiki/Degenerate_energy_levels

    The energy levels in the hydrogen atom depend only on the principal quantum number n. For a given n , all the states corresponding to ℓ = 0 , … , n − 1 {\displaystyle \ell =0,\ldots ,n-1} have the same energy and are degenerate.

  7. Bohr model - Wikipedia

    en.wikipedia.org/wiki/Bohr_model

    An electron in the lowest energy level of hydrogen (n = 1) therefore has about 13.6 eV less energy than a motionless electron infinitely far from the nucleus. The next energy level (n = 2) is −3.4 eV. The third (n = 3) is −1.51 eV, and so on.

  9. Excited state - Wikipedia

    en.wikipedia.org/wiki/Excited_state

    Atoms can be excited by heat, electricity, or light. The hydrogen atom provides a simple example of this concept.. The ground state of the hydrogen atom has the atom's single electron in the lowest possible orbital (that is, the spherically symmetric "1s" wave function, which, so far, has been demonstrated to have the lowest possible quantum numbers).
