MLO2-1 Utilize the electromagnetic spectrum to distinguish and convert between wavelength, frequency and energy of different types of radiation.
MLO2-2 Distinguish how light and spectroscopy lead to the understanding of the electronic structure of an atom (Bohr and Quantum model).
MLO2-3 Apply quantum number (principal, angular momentum, magnetic and electron spin) rules to determine allowable values for each type of quantum number and how the quantum numbers relate to atomic orbitals.

Tyler DeWitt - This video is about the different ways that scientists have pictured the atoms over the years. It starts with Democritus and Leucippus, the first philosophers to discuss atoms. Then John Dalton did experiments on atomic theory. J.J. Thompson proposed the plum pudding model of the atom when he discovered electrons, and Ernest Rutherford countered with the nuclear atom when he discovered the nucleus in the gold foil experiment. Niels Bohr imagined that electrons circled the nucleus in orbits, and Erwin Schrodinger's quantum mechanical model pictures electrons buzzing around in orbitals.

Representing the Atom: Bohr Rutherford and Lewis Diagrams https://youtu.be/RleMc0BWEbM
Mr. Key briefly reviews the structure of the atom, constructing Bohr-Rutherford diagrams and Lewis structures (electron dot diagrams) for neutral elements.
Quantum Mechanics of the Electron https://youtu.be/t8mMN2X5_Vw
Professor Dave Explains - We don't have to know too much physics to do chemistry, but the electron, the particle that makes all the chemistry happen, is a quantum mechanical particle, so we have to understand it just a little bit. Don't worry, no math, just conceptual weirdness, followed by compelling monologue. Someone give me a TV show!
Quantum numbers | Electronic structure of atoms | Chemistry | Khan Academy https://youtu.be/KrXE_SzRoqw
Khan Academy Organic Chemistry Definition of orbital as region of high probability for finding electron, and how quantum numbers are used to describe the orbitals. Compares Bohr model orbits and quantum mechanical model of atom.

Professor Dave Explains - Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD you will know what they are. But let Professor Dave give you a head start!
