WebbBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr's model calculated the following energies for an electron in the shell, n. n … WebbBohr’s model treats the electron as if it were a miniature planet, with a defined radius of orbit and momentum. This assumption is a direct violation of the uncertainty principle , a …
WebbProblems with the Bohr Model It violates the Heisenberg Uncertainty Principle because it considers electrons to have both a known radius and orbit. The Bohr Model provides an incorrect value for the ground state orbital angular momentum. It makes poor predictions regarding the spectra of larger atoms. What are the postulates of Bohr’s model ... In the early 20th century, experiments by Ernest Rutherford established that atoms consisted of a diffuse cloud of negatively charged electrons surrounding a small, dense, positively charged nucleus. Given this experimental data, Rutherford naturally considered a planetary model of the atom, the Rutherford model of 1911. This had electrons orbiting a solar nucleus, but involved a techn…
