HS-PS1-8. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
HS-PS3-2. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects).
Read Chapter 4.3 Modern Atomic Theory pg 113-118. Outline the reading in your science notebook and include major points and diagrams/tables.
you should focus on the following essential questions:
- What can happen to electrons when atoms gain or lose energy
-What model do scientists use to describe how electrons behave in atoms
-What is the most stable configuration of electrons in an atom
