In today's class, Andrew learned about the octet rule and how it applies to individual elements. He also learned how to write lewis structures for both elements and compounds. Andrew did very well with the new challenging information.
We read an article reviewing octet rules and the Lewis structure of atoms and molecules. Andrew read how Lewis structures are drawn, using lines to represent bonded pairs of electrons. When his 15 minute break was scheduled, during the latter part of the session, Andrew requested, and was given, permission to study for his art test, which he will be taking later today.

Lesson Comments
I subbed for Nicole this morning, Friday, 11-18-22, from 9:45 - 10:30, in Science.
Review physical properties of known acids.
Write the formula of 5 common lab acids.
Discuss the term ionization
Show the ionization of each acid when placed in water.
Elicit what ion is common to each ionization.
State the Arrhenius definition of an acid.
Repeat using 5 base formulas
State the Arrhenius definition of a base.
In today's class, we discussed nuclear chemistry, including fusion, fission, carbon dating, tracers and imaging. Andrew did very well with the new information and was able to answer all of the review questions I had for him at the end.
During today's classes, we described the Bohr model of the hydrogen atom. We discussed Lousie de Broglie's role in the development of the quantum model of the atom, compared and contrasted the Bohr model and the quantum model of the atom, and finally, we explained the Heisenberg uncertainty principle and the Schrodinger wave equation led to the idea of atomic orbitals.
In today's class, we discussed the half-life of elements, including talking about what half-life is, what it does, and how to calculate it. Andrew was able to do practice problems at the end and did very well answering the questions I had for him.
During today's classes, we started working on Chapter 4.
We explained the mathematical relationship between the speed, wavelength, and frequency of electromagnetic radiation. We discussed the dual wave-particle nature of light and discussed the significance of the photoelectric effect.
