CHEM 112 Lecture Notes - Lecture 4: Covalent Bond, Lewis Acids And Bases, Bohr Model
Document Summary
Lecture 4 unit 2 quantum mechanics and electrons in atoms. Constantly charge particles give of electromagnetic radiation. Hydrogen emits 4 lights, red, yellow and 2 different blue tones. Bohr model only works with 1 electron . Stop treating electrons like a particle, treat it like a wave. Einstein believe light was a wave and a particle. De broglie believe if light waves can be particles, then matter can also be matter waves. Matter has wavelength, just like light (people laughed at de broglie for his theory) Studied diffraction patterns to fry to see if matter exhibits wave-like behaviour. Wave function is saying you would nd particles more likely in the centre (where the hills and valleys are) rather than the ends. Electrons in atom work in 3-d space. N = principle quantum #; determines the energy of the orbital. L = angular momentum quantum #; take positive integer values from 0 to n-1; determines the shape of orbital.
