Welcome to Unit 2! Check Schoology for new due dates! All work done by the end of MP1 (10/31)!
Unit Overview
This unit continues our exploration into how atoms work, but focuses on electrons and their impact on the behavior of the atom, whereas the previous unit focused on the nucleus. While understanding nuclear behavior is important and interesting, it is the organization or arrangement of electrons that determine most of the properties of an element.
In this unit we will further explore two different models to represent the arrangement of electrons, and understanding these arrangements will be key in understanding the chemistry of elements later in the year.
In Bohr's earlier model you will find a lot of very familiar information and techniques that you have likely seen in earlier science classes. The later Schrodinger Model arrangements are more complex and definitely will be new content. These models, however, show information we don't see in the Bohr Model, and can therefore explain chemical phenomena that the earlier Bohr Model cannot.
Finally, we will explore some applications of these electron configurations, and will use the arrangements of electrons to explain chemistry for the first time. Early in the unit we will learn about the Periodic Table, and see how it is organized to match the arrangement of electrons in atoms. We will also experiment with a process called spectroscopy that uses light to explore the inner structure of the atom.
