In today's class, Andrew learned about electron configuration, including what it is and how to find it for each element in the periodic table. We watched a video, did some notes, and then followed that with some practice problems. Andrew did very well.
Discuss isotopes, radioactive isotopes, and nuclear stability.
Introduce alpha particles, beta particles, and gamma rays.
Use examples to demonstrate alpha emission decay and how to determine the new nuclear element formed by the decay.
Define a beta particle as a high energy electron, use the symbol and demonstrate how to determine the new nuclear element formed when beta emission occurs.
Analysis of exothermic and endothermic reaction rate graphs.
Discussion of factors which influence he rate of a reaction. These include the activity reactants, the temperature, the concentration, and the particle size.
Today, we started working on Chapter 3. We explained the law of conservation of mass, the law of definite proportions, and the law of multiple proportions.
In today's class, we finished our discussion on avogadro's number and the mole, including what they are, how to calculate them, and how they are used in chemistry. We also watched a video on molar mass and did some practice problems on how to determine them for different compounds.
Introduction to nuclear chemistry; The discoveries of Roentgen, Becquerel, and Curie.
Define radioactivity, radiation, isotope, radioisotope, and radiation decay.
Introduce the alpha particle, its makeup, charge, and strength.
