About This Chapter
Types of Elements - Chapter Summary
The video lessons in this course introduce middle school students to working with the periodic table. Students learn about the different elements on the table as well as how their properties and characteristics determine their placement on the table. Each video is 5-10 minutes long and presents the science concepts in a fun way that is easy for them to understand and remember. There are also multiple-choice quizzes and an end-of-chapter test available that you can use to test their comprehension of the types of elements.

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. Metals on the Periodic Table: Definition & Reactivity
Look around for a second...how many metallic things can you see? Generally when we think of metals, we think of substances that are shiny and durable; however, they're also in our food and in our bodies. Learn what makes a metal a metal and why metals are special.
3. 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!
4. Alkaline Earth Metals: Definition, Properties & Characteristics
Column 2A of the periodic table is home to the reactive alkaline earth metals. We find these elements in fireworks, vitamins, and even running through our own veins. Learn some properties and characteristics of this group of elements, and then take a quiz.
5. 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.
6. Alkali Metal Elements: Properties, Characteristics & Reactions
What happens when you put a chunk of an alkali metal in water? Fire, of course! Learn the characteristics of this interesting chemical family, examine some typical alkali metal reactions, and then quiz yourself on your new knowledge.
7. Noble Gases: Definition, List & Properties
Elements are grouped on the periodic table based on their chemical properties. In this lesson, you will learn about a group of elements known as the noble gases and their unique properties.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
