About This Chapter
Properties of Alkali & Alkaline Earth Metals - Chapter Summary
Use the videos in this chapter to expand your knowledge of the types and features of alkaline earth metals. You will learn about atomic and ionic radii and trends on the Periodic Table, what happens in the body when electrolytes, such as sodium, potassium and chloride, are incorrectly balanced, and much more. Successful completion of the chapter should enable you to:
- Name the characteristics of alkaline earth metals
- Understand the trends present among the periods and groups on the Periodic Table
- Detail metals and halogens on the Periodic Table
- Explain the properties of compounds
- Discuss the symptoms of electrolyte deficiency and toxicity
- Describe the formula and reactions to sodium hydroxide
- Identify the types, uses and properties of limestone

The convenient online platform allows you to work at your convenience and at your own pace. You can study from your desktop, laptop, tablet or notebook computer in any location that offers Internet access. You can even work from your smartphone!
1. 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.
2. 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.
3. 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.
4. Halogens on the Periodic Table: Properties, Reactivity & Uses
Elements are grouped into families on the periodic table based on their chemical and physical properties. In this lesson, you will learn about a unique group known as the halogen family.
5. Physical & Chemical Properties of Compounds: Types & Examples
Compounds are made up of elements that are chemically joined. Like elements, compounds have properties that allow us to identify them. Learn about physical properties, like color, odor, melting point and boiling point, as well as chemical properties in this lesson.
6. Sodium, Potassium & Chloride: Electrolyte Deficiency & Toxicity Symptoms
Sodium, potassium and chloride are electrolytes needed by your body for proper fluid balance, nervous system function and heart function. Learn how they are regulated and what happens if there are too few or too many in your body in this lesson.
7. What is Sodium Hydroxide? - Formula & Reactions
While handling sodium hydroxide can be dangerous, knowledge of sodium hydroxide can be enriching. Learn what sodium hydroxide is, its formula and about some chemical reactions involving sodium hydroxide in this lesson.
8. What is Limestone? - Properties, Types & Uses
In this lesson, learn about limestone, a calcium carbonate-rich chemical sedimentary rock. There are several varieties, including fossil containing rocks, which can be found all over the world. It has numerous uses, particularly as a building material.
