Schedule to Exam 1
| Date | Day | Topics |
|---|---|---|
| 8/25 | Mon | no class |
| 8/27 | Wed | Class Introduction. Went over class info - website, syllabus, grading, iclickers, etc... |
| 8/29 | Fri | Will finish up on class structure and info. More discussion about Quest and homework. FUNDAMENTALS!!! Catch up if you're behind on the fundamentals. These are what Chapters 1-4 are about. There will be 3 homeworks on the fundamentals. Get 'em downloaded and go to town. |
| 9/1 | Mon | Labor Day - no class |
| 9/3 | Wed | Homework 4 is up and ready now. Introduce Chapter 12 on Atomic Theory. Electromagnetic radiation. Planck's constant. Light as wave and particle. Discussed the interaction of EM radiation with matter (molecules). The Work function (Φ). De Broglie. |
| 9/4 | Thu | H01 is due by 11 PM. |
| 9/5 | Fri | more Chapter 12 - De Broglie and particles as waves. Looked at the
line-spectrum for hydrogen (both absorpsion and emission spectra). Balmer vs Lymann series.
Energy levels within the H-atom and electron energy "jumps". The Rydberg Equation. This is
really equation 12.1 in your book on page 520. Zumdahl's equation 12.1 is for the energy (in joules)
of each level (n = 1, 2, 3,...). To get changes for the electron "jumps" you need to calculate
En for the 2 levels of the jump and then take the difference. OK... here's the Rydberg Equation (with R defined): 
(note that this is a frequency, not energy) Also covered (started) the concept of Particle-in-a-box. |
| 9/8 | Mon | Chapter 12 - I talked more about the wave function Ψ (psi). A bit more on particle in a box and then looked closer at the Schrondinger equation and its solution. When the Schrodinger equation is solved for 3 dimensions you will end up with 3 Quantum numbers. We looked at the "rules" of this 3 quantum numbers (n, l, and ml). We also included the 4th quantum number ms. |
| 9/9 | Tue | H04 is due by 11 PM. |
| 9/10 | Wed | H02 is due by 11 PM. Looked more closely at Ψ. Broke it into parts: the radial (R(r)) part and the angular part (Θ(θ) and Φ(φ) or Y(θ,φ)). Also DREW pictures of the radial function AND the radial distribution function. Learned that there are nodal surfaces for the wave functions: planes, cones, and spheres. You can even know how many of each following the rules: total nodal surfaces = n - 1 nodal planes and cones = l (that's "ell", the angular momentum quantum number) nodal spheres = (n-1) - l (that's what is left after you count the planes and cones) Also showed off Dr. Richard Spinney's Web Site (from Ohio State) that has wonderful 3D plots of the hydrogen atomic orbitals (and more!). |
| 9/12 | Fri | H03 is due by 11 PM. Went over some more about orbital shapes. Looked at the Orbitron web site (see under links) and viewed pictures of various orbitals - even the 7g orbitals. Then looked at the energies of the orbitals for H-atom and how those changed to even lower energies as we added protons and electrons. I made the point (this is an understatement) that 2 electrons are the maximum number in ANY single atomic orbital. Learned the Aufbau filling order and told to USE the periodic table. How to write out electron configurations. You were told to KNOW the exceptions in the filling order for chromium and copper which yield s1d5 and s1d10 respectively and NOT s2d4 and s2d9. |
| 9/15 | Mon | Basically finished up Chapter 12. Started class by visiting "David's Whizzy PT" which is found under my LINKS page and under the "Physics 2000" at the University of Colorado. We qualitatively watched as electrons populated the orbitals in the atoms of the periodic table. Each time we added electrons we watched the orbitals sink to lower energies. Why? Because more protons are there to attract those electrons. This trend was linked to ionization energy trends and to atomic radius. ALL our trends tend to have their extremes at the 2 corners of the periodic table - the top-right corner and the bottom-left corner. The trends you need to know for the exam are atomic size (both for neutral atoms and for ions), ionization energy, and for electron affinity. |
| 9/16 | Tue | H05 is due by 8 AM. due to slow downs on Quest the due date/time was moved to here. |
| 9/17 | Wed | Review a bit for Exam 1 - Chapter 12 recap - introduce Chapter 13. |
| 9/18 | Thu | EXAM 1, 7-9 PM |
| 9/19 | Fri | Talk like a pirate day! Talked like a pirate a bit. Then went over the exam averages and the 4 most missed problems. Then started on Chemical Bonding... which, to my surprize was actually "Chemical Boning" on my slide. There was much laughter... after one minute of confusion I finally got the joke. Moving on, I discussed the importance of ionic bonding and covalent bonding. Nomenclature will also be important on Exam 2 - so start memorizing those ion names. |
