Bohr's model of an atom (video) | Khan Academy
Learn about Bohr's model of the atom and its significance in understanding atomic structure.
Emission spectrum of hydrogen (video) | Khan Academy
The Balmer Rydberg equation explains the line spectrum of hydrogen. A line spectrum is a series of lines that represent the different energy levels of the an atom. In this video, we'll use the Balmer-Rydberg equation to solve for photon energy for n=3 to 2 transition

In this exercise, we will practice questions related to the line spectrum and Bohr's model for hydrogen atom.
Bohr model radii (derivation using physics) - Khan Academy
Learn about the Bohr model of the hydrogen atom and the physics behind it. Use equations such as Coulomb's law and Newton's second law, along with the assumption that angular momentum of an electron is quantized, to calculate the radius of the atom for a ground state electron.
