Introduction to solid state Chemistry - Lecture 3 - Donald R. Sadoway
Atomic Spectra of Hydrogen and Matter/Energy Interactions Involving Atomic Hydrogen
Prof. Sadoway talks about the principles of modern chemistry and how that led to the understanding of the structure of the atom. He details Bohr's postulates for the hydrogen atom and discusses how the Planck-Einstein relationship applies to electron transitions. He defines the different isotopes of hydrogen.
This lecture includes the following:
J. J. Thomson's "plum pudding" model
Electrons are distributed uniformly throughout the atom
Ernest Rutherford's "nuclear" model
Conclusions from the gold foil experiment
Majority of the mass is found in the nucleus
Electrons orbit around the nucleus
Niels Bohr's quantization condition
Explanation of blackbody radiation and atomic spectra
Electrons follow circular orbits around a nucleus
Orbital angular momentum is quantized hence only certain orbits are possible
Electrons in stable orbits do not radiate
Electrons change orbits by radiating or absorbing photons
