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. The Electron Shell
You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?
3. 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.
4. 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.
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. 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.
7. 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.
8. 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!
9. What is Barium? - Definition, Uses & Formula
Did you know the element barium was given its name because it was so big? Explore this lesson to learn all about barium and its common uses. When you are through, take a short quiz to see just how much of an expert you are about all things barium.
10. What is Titanium? - Properties & Uses
Have you ever wondered how airplanes can be so strong? Or have you wondered how toothpaste gets its color? The same metal is responsible for both properties. In this lesson we will learn more about the element of titanium.
11. Ferrous Metal: Definition & Examples
Ferrous metals have many important uses - chances are you've seen a ferrous metal today! This lesson will define ferrous metals, list some properties, and then conclude with examples.
12. Heavy Metals: Definition & Examples
In this lesson, you'll learn what heavy metals are. After reviewing the definition, we'll look at four examples: lead, copper, mercury and arsenic. We'll cover where these elements are found and how they affect the environment and human health.
