Niels Bohr: His Life and Work as Seen by His Friends and Colleagues. Suspended in Language: Niels Bohr’s Life, Discoveries, and the Century He Shaped. 6.1, “Waves and Electromagnetic Energy.” Electrons change orbits by radiating or absorbing photons.Electrons in stable orbits do not radiate.Orbital angular momentum is quantized hence only certain orbits are possible.Electrons follow circular orbits around a nucleus.Explanation of blackbody radiation and atomic spectra.Majority of the mass is found in the nucleus.Conclusions from the gold foil experiment.Electrons are distributed uniformly throughout the atom.He defines the different isotopes of hydrogen. He details Bohr’s postulates for the hydrogen atom and discusses how the Planck-Einstein relationship applies to electron transitions. Sadoway talks about the principles of modern chemistry and how that led to the understanding of the structure of the atom.
