Fri.....Fri....
D,G: we finished our explanation of how the Bohr Model accounts for the bright-line emission spectrum of Hydrogen and SOME of the emission lines of the other elements. However, Bohr's model didn't account for many of the energy differences that electrons experience when they undergo electron transitions. This had to do with electron-electron repulsion and also the fact that electrons also behave as.....WAVES! More on that on Monday as we do the quantum mechanical model of the atom.
We will have our next two tests on Thursday and Friday: one test is written response on atomic structure including the Bohr and Quantum Mechanical Models of the atom and the other test is multiple-choice on atomic concepts, matter, and energy. On the following Tuesday, the last test will assess what you learned in lab this quarter: it will be a multiple choice test on lab techniques and skills covered in our labs this quarter. So, you have at least 300 more points to earn this quarter.
E: We finished electron configurations and orbital diagrams for the first three periods of the periodic table. That's about as far as we can go with the Modern Quantum Mechanical model of the atom. (Of course, if you're curious, at extra help, you can always ask further questions about the model). We will be tested on the Bohr and Modern models as well as on question types that the class did not master from the last test....SOON. Maybe 5 people ( I congratulate these students who are clearly trying and regularly come to some of the DAILY opportunities for extra help) have come in to correct their last tests. The rest of you, what are you waiting for? This material is on the Regents so you should want to learn or clarify what you didn't learn before the last test. You will see those question types again. There is plenty of practice material assigned in the hw over the weekend. Do that hw and check your answers, you will be tested on it soon! We will do review on Monday so MAKE SURE that you have your blue and orange review books (do NOT tell me you forgot them after the bell has rung) as well as the blue text exercise manual.
For additional points to your average, I am assigning a graded hw. On page 1 of your orange review book, there is a list of chemistry vocabulary that you must PRECISELY know and use on the Regents. For HW, due Tuesday, NEATLY WRITE OUT (in block letters if your handwriting is not good/clear; do NOT HAND IN ANYTHING THAT IS TYPED) the definitions of these terms. Use the glossary of these terms in the back of the review book or the text. DO NOT abbreviate; use complete sentences and, if you want to help yourself know these terms, write or draw an example of each term, if possible. Do this simple assignment correctly and hand it in by Tuesday or you will not receive credit.
AP: finished our Thermo unit with a light discussion about energy sources and consumption. Ironically, in life, this topic is paramount and drives just about EVERYTHING that affects you. Food, fuel, technology, competition, "quality of life" vs. living in a cave or with the Amish, these things will be your daily concern and perhaps daily interest if you become a chemical engineer or physical chemist.
Our test on Tuesday will cover the unit including the 0th and 1st Laws of Thermo, Calorimetry, Hess's Law in all of its forms, Hess Law diagrams, Bond energies/Enthalpy change estimations, as well as a gas unit question or two.
Have a good weekend....bring an umbrella.
