Bohr's hypothesis

WebBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus.

http://philsci-archive.pitt.edu/8335/1/Bohr WebThe 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. cost of tile shower vs prefab shower https://myshadalin.com
