About This Chapter
Who's it for?
This unit of our AP Chemistry Homeschool course will benefit any student who is trying to learn about the significance of the arrangement of elements on the periodic table. There is no faster or easier way to learn about the periodic table of elements. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about the structure of the electron shell, groups and periods of elements, and patterns of shared characteristics among elements.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a chemistry curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a periodic table of elements unit exam confirm understanding or identify any topics that require review.
The Periodic Table of Elements Unit Objectives:
- Discuss how elements are arranged into groups and periods and how elements in those classifications share some common physical properties.
- Describe the parts of the electron shell, including energy level, valence level, and valence electron.
- Identify the relationship between an element's place on the periodic table and its valence electrons and energy levels.
- Evaluate how atomic radii changes across periods and down groups on the periodic table of elements.
- Outline trends in ionization energy across periods and down groups on the periodic table.
- Discuss the relationship between electronegativity and an element's place on the periodic table.
- List additional characteristics, such as boiling point and metallic properties, that trend up or down depending on placement on the periodic table.
- Understand differences between transition metals and main group 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. 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!
