AP classes. Finished electron configuration. All classes have a lab day, a review day and a skip day between Thursday, Friday and Monday. Test is Tuesday.
H8: Electron configuration: noble gas short cut, d block (row-1), d4 and d9, f block (row -2), and ions (both positive and negative)

Tuesday, October 20th
AP4: the meaning of l (lower case L) and n. Numbers of nodes and orbital types. How they all fit together and a one-dimensional energy graph of orbitals.
AP1: fitting the orbitals all together, the energy graph and electron configuration (including the aufbau principle and the Pauli Exclusion Principle…Hund’s rule still to come)
H8: periodic table project (in groups) and electron configuration.

AP3 and AP4 : Double Salt Lab

AP3: psi squared graphs into orbitals, angular nodes and orbital types, radial nodes and energy levels
AP4: waves, schrodinger’s equation, quantum numbers, psi graphs and the s orbital
AP1: orbitals, angular nodes and orbital types, radial nodes and energy levels
H8: Heisenberg, two facts that we know from the “non-notes” stuff, Schrodinger, orbitals

AP4: Almost no time at all. Talked about problems with Bohr’s theory.
H8: Beer’s law lab – you need to graph your data (absorbance v. concentration) give me the equation for the graph in correct form and then use that equation to find the concentration of the unknown. You also need to write a paragraph of theory that answers the two questions: 1. As light travels through the solution, some light is absorbed — what happens to that light? and 2. why do solutions get darker as they get more concentrated? This lab (the graph calculations and paragraph) are due MONDAY.
Yes, you have another polyatomic ion quiz tomorrow.
AP1: psi graphs, and rotating a psi squared graph through three dimensions
H8: Weird stuff that you aren’t allowed to take notes on…

AP3 and AP4: double salt lab
H8: Bohr theory – answers to the 4 questions, problems with Bohr’s theory
October 8, 2009
Thursday, October 8th
AP4: started modern electron theory (light as a wave, photoelectric effect with Al Einstein, de Broglie and the dual nature of light and matter, and Heisenberg’s uncertainty principle).
AP1: started Schrodinger. discussed waves, the Schrodinger equation, variables, and graphs of psi, psi squared and 4 pi r squared psi squared graphs for n=1.
H8: problems with the atom, spectrum tubes, flame test lab (you need to turn in your observations of color and the identity of A, B, and C), spectrum tube lab (turn in observations and measurements, calculate frequency and energy of one line from each tube and for all three lines from the hydrogen tube), and we discussed the “problems” that led to Bohr’s work.
