About This Chapter
Who's it for?
Anyone who needs help learning or mastering college-level general chemistry material will benefit from taking this course. There is no faster or easier way to learn college-level general chemistry. Among those who would benefit are:
- Students who have fallen behind in understanding the properties of groups and periods or working with atomic and ionic radii
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the periodic table
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Periodic Table chapter exam.
Why it works:

Students will review:
This chapter helps students review the concepts in a Periodic Table unit of a standard college-level general chemistry course. Topics covered include:
- Valence electrons and energy levels of atoms of elements
- Trends among groups and periods of the periodic table
- Ionization energy
- The diagonal relationship
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Transition Metals vs. Main Group Elements: Properties and Differences
Which is better: to be steadfast and consistent or to be a colorful chameleon? This lesson compares and contrasts the main group elements and the transition metals. Then make your own decision!
8. Francium: Definition & Uses
Explore this lesson to learn about the element francium, a radioactive element that is very rare. Understand how francium was discovered and why it is not widely used in commercial and industrial applications.
9. Actinide Series: Elements & Periodic Table
The actinide series includes elements 89-103. In this lesson, we will learn what characteristics these elements share, how they are used, and how they were discovered.
10. Lanthanide Series: Elements & Periodic Table
This lesson introduces the elements that are in the lanthanide series of the periodic table. The identity of the elements, uses, and properties are also discussed.
11. Lanthanides: Electron Configuration & Oxidation States
This lesson will provide the names and electron configuration of the fifteen lanthanides in the periodic table. It will also discuss the reason why they have a stable oxidation state of +3.
