About This Chapter
Metals Overview - Chapter Summary
In this chapter on metals, engaging lessons cover subjects like metal reactions, alkali metal elements, and copper extraction. You can also get an understanding of metals on the periodic table. After going through the lessons, you should be able to do the following:
- Compare the properties of iron and bronze
- List contemporary uses of metals and alloys
- Discuss methods of extracting metals
- Identify a single replacement reaction
- Recall properties of alkaline earth metals
- Discuss steps for recycling aluminum
- List types and uses of ore
- Explain how mining impacts the environment
A short quiz is available to test your knowledge of each lesson, and the quizzes can be printed. The quizzes link back to specific topics, so if you get a question wrong you can easily go back and review that topic. Another nice feature is that you can submit questions to our instructors if there are any topics you don't understand.
1. Iron vs. Bronze: History of Metallurgy
This lecture explores the transition from the bronze age to the iron age. The difficulties of working with iron are enumerated. The properties of iron and steel are compared to those of bronze. Finally the implications for this transition on civilization are considered.
2. Metals: Occurrence, Processing & Extraction
While metals are a huge part of our lives, we probably don't think much about where they come from. This lesson explores where ores can be found and how they are processed in order to separate out the parts of the ore that can be utilized.
3. The Activity Series: Predicting Products of Single Displacement Reactions
Discover what a single replacement reaction is and how to identify it. Learn what chemical activity is, how that applies to an activity series table and how to predict the product of a single replacement reaction by referring to the activity series.
4. Metal Reactions: Dilute Acids, Water & Oxygen
There are several categories of metals. Some are highly reactive and some aren't very reactive at all. In this lesson, we will go through the different metals and how they react with acids, water, and oxygen.
5. 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.
6. 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.
7. 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.
8. How to Recycle Aluminum
Most everyone is familiar with recycling. But what happens when the cans leave the bin and go off to the recycling plant? Today, we're going to find out how aluminum is recycled and how the costs compare to extracting new aluminum for our cans and containers.
9. What is Ore? - Definition, Types, Uses & Examples
Learn about ores, which are a special type of rock from which we can economically extract valuable elements and minerals. Ores are the source for some of the world's most important geological resources, including both precious and industrial metals and energy resources like uranium.
10. What Distinguishes Ore from Other Mineral Deposits?
Ore deposits provide the raw materials that allow our society to function. In this lesson, we'll look at the driving forces that cause ore deposits to be unique from non-valuable mineral deposits.
11. Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use
In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.
