2/1 – Wednesday – A Day – 2/3a Lab, 4
a) To discuss the Bohr model of the atom and its combination of classical physics and the new quantum theory.
b) To observe emission spectroscopy and make calculations with the Balmer Equation
c) To identify elements by their Emission Spectrum
Period 2/3a: – Bohr, Balmer equation, inverse square law – demo, quantum leaps
1. Complete the light theories, positive and negative, colorblindness, newton wheels, sunset demo
2. Introduce the Bohr Model, plane, Balmer equation, inverse square – law, quantized energy levels TUBE, phosphorescence demo
3. Bright line Spectrum Demo, absorption spectrum, transition of electrons flash
Period 4: Bohr, Balmer equation, inverse square law – demo, quantum leaps
1. Review light theories, positive and negative, trick the eyes too see white
2. Introduce the Bohr Model, plane, Balmer equation, inverse square – law – quantized energy levels TUBE, phosphorescence demo.
3. Bright line Spectrum Demo /absorption theories.

Bohr took Plank’s and Einstein’s ideas as was the first to make a quantum model of the atom that stated that electrons can only have discreet energy levels (quanta) and that when they move (quantum leap) the energy changes result in photons of light being released (when moving back to the ground state) or absorbed (when moving to higher energy states). Before Bohr the model of the atom was Rutherfords, where electrons orbited the nucleus but could have any energy
|
Niels Bohr accomplishment was to describe the known Bright Line Spectrum of Hydrogen in terms of emissions of photons of light of specific energy related to electrons returning from an excited state (from a constant supply of energy). The red line in the Bright line spectrum below is due to electrons “leaping” from the 3rd energy shell back to to the second! Our homework is actually the calculation of the energy of the that this quantum leap or transition would release. It is this type of calculation that earned Niels Bohr a Noble Prize!

1. Complete the Timeline of the Clash of the Titans – due Monday – hardcopy or digital.
2. Complete the Form below. You will need the watch the to the end of the Clash of the Titans to complete. You will have one submission to this form.
3. Watch the quantum number lesson video and complete the form. This reviews the solutions to the Schrodinger equation that will allow us to determine the energy and relative positions of the electrons around the nucleus based on their quantum energy states. All this means is that we will get electron configurations from the equation FROM the solutions to the Schrodinger equation.
You learned electron configurations this summer and did so without the rest of the atomic structure history and concepts. We will re-vist electron configurations but will develop the concepts through quantum numbers!
