About This Chapter
OAE Chemistry: Atomic Theory and the Periodic Table - Chapter Summary
The quick lessons in this chapter are a useful tool for refreshing your knowledge of the periodic table and atomic theory before you register for the OAE Chemistry exam. The lessons in this chapter prepare you for questions about:
- The atom and early atomic theories by Dalton, Thomson and Rutherford
- Electron configurations
- Atomic spectra and the Bohr model
- Properties and groups of the periodic table
- Atomic and ionic radii and ionization energy
- Diagonal relationship and metallic character
Each video in this series can be viewed in about 5-6 minutes, so you can watch videos when you have time, whether on the go with your mobile device or at home or work with your laptop. These lessons give you a quick review of topics from your college courses that you might have forgotten or just want a refresher on before the exam. A transcript comes with each lesson, so you can easily reference important terms and concepts.
Objectives of the OAE Chemistry: Atomic Theory and the Periodic Table Chapter
Aspiring chemistry teachers in Ohio will need to take the OAE Chemistry exam to demonstrate their knowledge of essential chemistry topics before earning a teaching license. The exam is divided into five competency domains and is composed entirely of multiple-choice questions. Your knowledge of atomic theory and the periodic table will be tested in the matter and atomic structure domain, which makes up 18% of the exam. The exam could require you to make calculations to find the right answer, read a passage before choosing the best response or observe formulas and answer questions about them.
Our lessons come with quizzes that you can use to check your knowledge of the material and to become familiar with the format of the exam's questions before test day.
1. The Atom
Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?
2. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan
Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.
3. Electron Configurations in Atomic Energy Levels
This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.
4. The Bohr Model and Atomic Spectra
Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.
5. Valence Electrons and Energy Levels of Atoms of Elements
The periodic table contains a wealth of information. This lesson will explain how to use it to quickly determine the most useful information about the most important electrons. We will be focusing our discussion on valence electrons and energy levels.
6. The Periodic Table: Properties of Groups and Periods
How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.
7. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table
Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.
8. Ionization Energy: Trends Among Groups and Periods of the Periodic Table
Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.
9. Electronegativity: Trends Among Groups and Periods of the Periodic Table
How is fluorine like a child that doesn't share his or her toys? Find out in this video on electronegativity where we will discuss group and periodic trends among the elements.
10. The Diagonal Relationship, Metallic Character, and Boiling Point
What may have once seemed like a bunch of random squares with letters in them is now shaping up to be one very organized chemistry reference. In this lesson you will discover three other trends that are found on the periodic table: the diagonal relationship, trends in metallic character, and trends in boiling point.
