Chem 1320 1st Edition Lecture 16Outline of Last Lecture I. Light Hitting MatterII. Albert Einstein and Elevator DoorsOutline of Current Lecture I. The Borgie HypothesisII. John BalmerIII. Neils Bohr and the hydrogen atomCurrent LectureI. The Borgie Hypothesis: light (particle behavior) Einstein= E=mc2Plank= E=hv/wavelengthmc2= hc/wavelength= m/h(wavelength) > cm= h/wavelength p= h/wavelength, P= momentum= mass x velocityII. John Balmer1/wavelength = 1.1 x 107m-1 (-1/z2- 1/h2) h= 3,4,5 specific to hydrogen III. Neils Bohr and the hydrogen atom“planetary” modelAssumptions:1. Only circular orbits (balance of forces)2. Electrons can move between orbitsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Results:1.
