1. Hydrogen atom; Bohr model
(a) Explain the model with figure
(b) Give examples of what you can explain and not to explain with the model
(a)
The Bohr model of the hydrogen atom or a hydrogen-like ion, where the negatively-charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits it is accompanied by an emitted or absorbed amount of electromagnetic energy. The orbits in which the electron may travel are shown as grey circles; their radius increases as , where is the Principle quantum number. The transition depicted here produces the first line of the Balmer series, and for hydrogen it results in a photon of wavelength 656 .Niel Bohr suggested electrons could only have certain classical motions:
