In this chemical bonding learning exercise, high schoolers read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then high schoolers complete...

Pupils are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

Students intergrate science, technology and society into exploring the periodic table. They investigate one element of their choice and write a one page paper on the elements discovery, properties, uses, and the effect on society.

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

In this elements worksheet, students review the periodic table and how the elements are organized in the periodic table. This worksheet has 5 short answer and 4 fill in the blank questions.

Identify the number of valence electrons of given elements.

A short assessment to see if you understand valence electrons in specific elements.

This tutorial investigates how to draw Lewis valence electron dot structures.

Detailed explanation of Valence Shell Electron Pair Repulsion (VSEPR) Theory with examples and questions for the reader to check comprehension. Also includes step-by-step instructions for correctly building molecules using VSEPR Theory....

[Free Registration/Login may be required to access all resource tools.] Valence electrons, their variation in the periodic table and relation to reactivity and electrical conductivity of elements.

A slide show presentation which demonstrates how to identify the number of valence electrons an element has based on its location on the periodic table.

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

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with hybrid orbitals and specifically the valence bond model.

This instructor led activity will produce a partially filled periodic table that contains electron-dot models for the first twenty elements in the appropriate boxes. It will be used as a visual tool for students to connect concepts such...

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...

Introduction to the concept of valence electrons that relates the idea to periodic properties and electron configurations.

Presents examples of molecules that do not match the expected bond angles in the Valence-Shell Electron-Pair Repulsion Model. Requires Java.

This lesson will describe the importance of valence electrons in the process of chemical bonding. It is 6 of 7 in the series titled "Valence Electrons."

[Free Registration/Login may be required to access all resource tools.] Covers valence shell electrons and inner shell electrons.

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

Brief explanation from Frostburg State University of valence bond theory and an explanation of what chemical situation creates a valence bond between two atoms.

This site from WebChem contains information on the subject of bonding with an emphasis on valence and core electrons.

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."

An excellent tutorial that examines VSEPR and pairs of valence electrons. The valence shell electron pair repulsion concept is explored using animated models. Includes a VSEPR calculator. Use the toolbar on the left to navigate through...
