Mon-Day 1
Physics - we reviewed for the quarterly, a test that counts towards your quarter grade; the quarterly MAY also replace your LOWEST test grade, so the quarterly grade CAN count twice.
Tuesday's test is WRITTEN RESPONSE. There will be FOUR QUESTIONS, two on straight-line motion, one on projectile motion, and one on forces/dynamics.
Wednesday, we'll have the multiple choice part of the exam: 25 questions, about evenly divided among the four units.
We reviewed for the quarterly, going over the unit on vectors, straight-line motion, and projectile motion. Forces/dynamics is also on the test.
Keep checking Blackboard for today's notes and updated past test written-response answers.
AP Chem- we discussed the solutions to the Schroedinger equation, which takes into account the wave and particle nature of the electron as well as all proton to electron attractions and electron to electron repulsions in ANY atom or ion!
The solved equation yields FOUR quantum numbers that indicated the energy (and APPROXIMATE LOCATION, most of the time) of an electron in an element. we discussed the inability of the Bohr Atomic Model to account for many of the emission lines in all elements except Hydrogen. We then looked at the basis of the Quantum Mechanical Model of the atom, which treat the electron as a particle and a wave and accounts of electron-electron repulsions.
The Schroedinger equation solves for the "allowed" energies of all electrons in an atom.
Each electron's energy and approximate region is described by four quantum numbers: n, l, m(l), and m(s).
We then saw that the principal quantum number limited the angular momentum/azimuthal quantum number to a certain range of values. We also saw that the azimuthal quantum number determines the possible number of orientations that the orbitals can have in space. Magnetic spin number can be only one of two values: + 1/2 and -1/2.
We then applied this new information to earlier orbital language i.e. s, p, d, and f sublevels are associated with the azimuthal quantum numbers 0, 1, 2, and 3, respectively.
We noted that only the n and l quantum numbers determine the energy of the electron in an atom. With this relative energy information, we will assemble the relative energy sublevel order of the electrons in any atom via the "Aufbau PrincipLE/RuLE".
