Tues-Day 2
AP Chem - we explicitly reviewed the reasons for the Aufbau Principle, Pauli's Exclusion Principle, and Hund's Rule. We then detailed the orbital diagrams and electron configurations for the elements in periods 2 and 3.
We finished with an exception to the Aufbau Principle, which we explained in terms of the miniscule 4s-3d energy difference, and the minimization of electron to electron repulsion that occurs when electrons are symmetrically distributed in a "subshell" i.e. among the degenerate orbitals of a given sublevel of energy.

Bio - we wrote out two detailed examples of frameshift mutations, showing the drastic changes in the amino acid sequence that typically ensues, thus resulting in a completely non-functional protein, and often in harm or death to a cell.
In 7/8, we did the transcription-translation-protein synthesis lab- big fun!# posted by C @ 1:21 PM
