- Define electronegativity and ionization energy
- Exhibit knowledge of the diagonal relationship, metallic character and boiling point
- List properties of s-block, p-block, d-block and f-block elements on the periodic table
Benefit from access to top instructors and subject-matter experts who can help you better understand elements and periodic table blocks without setting foot in a traditional classroom. Instructors provide in-depth analyses of this subject area, and subject-matter experts answer your questions about specific lesson topics. Multiple-choice quizzes and a practice exam are available to assess your knowledge of the lessons. Access these and other study resources anytime using any computer or mobile device with an Internet connection.
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. 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.
5. 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.
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. S-Block Elements on the Periodic Table: Properties & Overview
Take a tour of the s-block of the periodic table and get to know the elements inside. Learn all about the s-block elements, including some of their distinguishing properties, then quiz yourself on your knowledge.
8. P-Block Elements on the Periodic Table: Properties & Overview
Come on a tour of the p-block, an area on the periodic table filled with an incredibly diverse group of elements. Learn what the p-block elements are, discover some of their properties, and then assess your new knowledge with a quiz.
9. D-Block Elements: Properties & Electron Configuration
In this lesson, we'll explore the d-block elements, which are the transitional elements situated in the center of the periodic table of elements. Read on to learn about this block of elements as well as how they behave.
10. F-Block Elements on the Periodic Table: Properties & Overview
The periodic table is a highly organized collection of the basic characteristics for all elements known to man. The atomic structure and characteristics of f-block elements are somewhat mysterious. Here's why.
