"We discussed Nuclear Reactions, Atomic Structure, and Periodic Trends. We began with a brief overview of the Rutherford Experiment and its meaning, pausing to discuss the types of nuclear decay particles. We then talked about the types of subatomic particles, their mass and charge, and how the inequality of a neutron to a proton+electron informed Einstein's matter-energy equivalence. We discussed atomic notation, including mass number and charge. We discussed the relationship between mass number and atomic mass. We discussed weighted averages, correlating it at his request to another area (rotational equilibrium). We discussed why the # of protons is the defining characteristic of an element. We covered how to balance a nuclear reaction with mass and charge, using U-235 as an example. We then used that to examine the decay of Carbon-14. We discussed 1st- and zero-order decay processes in general. We then dove into the math, emphasizing the half-life over the decay constant. We had an impromptu and challenging session on understanding logarithms. We then moved on to atomic structure. We discussed the Bohr Model and the Photoelectric Effect in Electrostatic Potential Energy terms. We moved on to the quantum model, pausing to expand on the wave/particle nature of the electron cloud. We discussed all four quantum numbers in detail, including what information each added to the knowledge base. We discussed the Aufbau principle, Hund's rule, the Pauli exclusion principle, and orbital theory in terms of volume. We discussed the layout of the periodic tables, important groups in the table, and the behavior of metals, especially transition metals. We then moved on to periodic trends. We discussed the nature of the Z-effective, the factors determining Atomic Radius, and how they changed across periods and down groups. We closed with ionization and electron acquisition, their trends, and exceptions.
We plan on meeting tomorrow to continue with Electronegativity, Bonding, Intermolecular Forces, Ideal Gasses, and maybe the Thermo of Gasses. I have assigned him problems in Nuclear decay to beef up his log knowledge in a relevant context."
