During this exercise, practice finding the number of valence electrons in an element. [1:22]

Through a series of slide show presentations and a video lesson, strengthen your understanding of valence electrons. [2:46]

In this activity, students use a map of electron configuration and bingo chips to configure electrons for elements that are given on a problem card. Students will see patterns of elements and their valence electrons in relation to the...

This lesson will explain how to identify the number of valence electrons an element has based on its position on the periodic table. It is 3 of 3 in the series titled "Identifying Valence Electrons."

This colorful page goes over the proper techniques for writing Lewis structures for elements. This is a great place to begin learning how to write Lewis structures. When you are ready for a more advanced lesson, follow the link to learn...

Find out how energy level models are represented on the Periodic Table of Elements.

Students can use this chemistry tutorial to further their understanding of the families of elements on the Periodic Table of Elements.

This simulation shows a simple band diagram for metals for Group 1A and 2A and the transition series. Each metal's valence orbitals combine to create a band that is responsible for the element's properties.

Students interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom.

[Free Registration/Login Required] In this interactive you must place all of the students in their seats from back to front and see if you can figure out what element they would be if the rows of bus seats were the indicated electron...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students will explore how the form of the periodic table is related to electron configurations, which in turn influences chemical reactivity.

This lesson will demonstrate how to write the electron configurations for any element given its location on the periodic table. It is 3 of 3 in the series titled "Writing Electron Configurations."

This is a teacher's companion guide with lesson plans for the periodic table. It includes learning objectives, lecture notes, links to related sites, answers to frequently asked questions, and a glossary of related terms.

In this lesson, students are introduced to the 5 major types of chemical reactions. Each reaction type will be analyzed and specific examples will be noted. Students will then perform a lab investigation which includes each of the...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will sse the Periodic Table to identify and explain the properties of chemical families, including alkali metals, alkaline...

This site provides a detailed overview of atoms. Content explores an atom's structure, as well as what ions are, how atoms bond, what compounds are (including how to name compounds), and what isotopes are.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be able to determine the number of valence electrons for any element and draw an electron dot diagram for any atom....

Test your electron-configuration skills in this animated exercise. Practice writing the abbreviated configurations for some of the common elements on the periodic table.

This lesson will demonstrate how to identify an element and state the number of valence electrons given its electron configuration. It is 3 of 3 in the series titled "Interpreting Electron Configurations."

Nice concise chemical fact sheet with all the basics on radon. Very thorough.
