About This Chapter
Using the Periodic Table - Chapter Summary and Learning Objectives
In this chapter, your instructor will provide you with the key to using the periodic table: learning how it is organized. You'll find out why the 118 elements found on the chart, such as gold or oxygen, are arranged into columns and rows, according to their atomic numbers. Groupings of similar elements or families will also be explained, including how some families, like metals and nonmetals, are separated by staircases or zigzag lines.
Once you've learned how the table is organized, you'll see how it can also provide you with important information about chemical properties. For example, you'll be able to predict that the metals, which constitute the majority of the elements on the table, can be used to conduct heat or electricity and may be easy to bend. When you've finished watching the video and completing the online self-assessment quiz, you should be able to:
- Define the term 'period' as it applies to the periodic table
- Define the term 'group' as it applies to the periodic table
- Explain the meaning of the atomic number
- Locate family groups of elements on the chart
- Use the location of an element to identify its chemical properties
- Explain why, on some charts, two rows of elements are placed beneath the main table.

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.
