Bahasa Melayu: Model Bohr dari atom hidrogen menggambarkan elektron-elektron bermuatan negatif mengorbit pada kulit atom dalam lintasan tertentu mengelilingi inti atom yang bermuatan positif. Ketika elektron meloncat dari satu orbit ke orbit lainnya selalu disertai dengan pemancaran atau penyerapan sejumlah energi elektromagnetik hf.
The Sommerfeld model predicted that the magnetic moment of an atom measured along an axis will only take on discrete values, a result which seems to contradict rotational invariance but which was confirmed by the Stern–Gerlach experiment. This was a significant step in the development of quantum mechanics.

The Stern–Gerlach experiment was meant to test the Bohr–Sommerfeld hypothesis that the direction of the angular momentum of a silver atom is quantized. [ 14 ] The experiment was first performed with an electromagnet that allowed the non-uniform magnetic field to be turned on gradually from a null value. [ 1 ]
The Bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell model. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics and thus may be considered to be an obsolete scientific theory .
Bohr Model of the Atom. The Bohr model, proposed by Niels Bohr in 1913, is a revolutionary theory describing the structure of the hydrogen atom. It introduced the idea of quantized orbits for electrons, combining classical and quantum physics. Key Postulates of the Bohr Model. 1.Electrons Move in Circular Orbits:
