Because a sample of hydrogen contains a large number of atoms, the intensity of the various lines in a line spectrum depends on the number of atoms in each excited state. At the temperature in the gas discharge tube, more atoms are in the n = 3 than the n ≥ 4 levels.

1 paź 2024 · Emission lines for hydrogen correspond to energy changes related to electron transitions. The Bohr model works only for the hydrogen atom. Review. What happens when a hydrogen atom absorbs one or more quanta of energy? How do we detect the change in energy? What electron transitions are presented by the lines of the Paschen series?
20 wrz 2022 · What happens when a hydrogen atom absorbs one or more quanta of energy? How do we detect the change in energy? What electron transitions are presented by the lines of the Paschen series? Does the Bohr model work for atoms other than hydrogen?
When an electron in a hydrogen atom is in the first excited state, what prediction does the Bohr model give about its orbital speed and kinetic energy? What is the magnitude of its orbital angular momentum?
The energies of the electron in the hydrogen atom can be calculated by putting in integer values for n; n = 1, 2, 3, 4, … ∞. When an electron is in a higher energy level and falls to a lower energy level, light is emitted.
The spectral lines whose wavelengths are given by the Rydberg formula correspond to transitions of electrons from the orbital with \(n\)th lowest energy, into the orbital with the \(m\)th lowest energy.
Bohr’s model of the hydrogen atom explains the emission and absorption spectra of atomic hydrogen and hydrogen-like ions with low atomic numbers. It was the first model to introduce the concept of a quantum number to describe atomic states and to postulate quantization of electron orbits in the atom.
