Atomic and Ionic Radii: Trends Among Groups and Periods
| The location and energy levels of atoms;|
The trends in the movement of ionic and atomic radii on the periodic table
|Tuesday|| Ionization Energy: Trends Among Groups and Periods of the Periodic Table; |
Electronegativity: Trends Among Groups and Periods of the Periodic Table
| The movement of ionization energy on the periodic table;|
Explanation of electronegativity and a look at its movement across and down the periodic table
|Wednesday||The Diagonal Relationship, Metallic Character and Boiling Point||Other relationships on the periodic table|
|Thursday||Transition Metals vs. Main Group Elements: Properties and Differences||Main groups and elements of the periodic table|
|Friday||Classifying Substances by the Physical Properties||Characteristics that distinguish substances, such as hardness or melting temperature|
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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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!
8. Classifying Substances by Their Physical Properties
After watching this video, you will be able to explain what physical properties are and use them to classify some common substances. A short quiz will follow.
