Mid-week
We began our second quarter today. This quarter has LOTS of vacation days (during which you'll be doing LOTS of chem, oh yes!), even more than the first quarter; yes, that is possible even though this is our fourth abbreviated week in a row. Don't fall behind because we have to cover a lot of ground in the least amount of time.
G/D Honors: today we wrote out the electron configurations and orbital diagrams for the first three periods of elements. Tomorrow, we get to the transition metals and we will see two quirky but explainable (yes, here comes an explanation question!) exceptions to the Aufbau Principle. I'll also show you the easy mnemonic so that you can correctly organize an atom in increasing sublevel energy order even if you don't have a periodic table nearby...1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s... you'll see the pattern tomorrow....
After that, we have a few easily deduced numerical relationships to see and then we can move on to the next unit: The Periodic Table= good times.
E: We're deep into the Periodic Table; today we learned various group names and various miscellaneous facts that appear on the Regents: allotropes of oxygen (O2 and O3 i.e. oxygen and ozone), allotropes of carbon = diamond, graphite, and buckyballs,
the room temp liquid METAL = Mercury = Hg and the room temp liquid non-metal = bromine = Br. We then discussed properties of metals vs. properties of non-metals: you guessed it, metals and non-metals have opposite characteristics.
AP: We continued with allowed quantum numbers that give the allowed quantized energies of an electron in an atom. We then did a photoelectric effect problem that last year's class couldn't do. Next, we started electron configurations in accord with the Aufbau Principle, the Pauli Exclusion Principle, and Hund's Rule.
We have a test when we come back from our three day weekend. I'll be at extra help tomorrow afternoon (as always) if you have practice questions that you want to go over. The test will be mostly on Quantum with a question or two about Thermo.
