Webelements offers a nice presentation on erbium, its properties, uses and history, along with basic data. Clearly presented.

A video and a short quiz on elements, how they combine through chemical reactions to make compounds, and how to write the chemical formulas for water and salt.

This lesson will define the Modern Period Law. It is 2 of 3 in the series titled "Modern Periodic Law."

A comic strip that features the element fluorine. Interesting, and a different approach to providing information.

A 1997 comic mentioning the element erbium. A good way to make learning about the elements fun.

A pair of comics that feature the element einsteinium. Fun ways to learn about chemistry!

Comics from the 1960's featuring the element arsenic. Not the greatest source of information, but interesting with some very nice visuals.

Experience chemical reactions with this virtual drag-and-drop laboratory. This site allows you to create chemical reactions by combining elements from the Periodic Table.

Review atoms with this slideshow. You can choose to listen to the review or read the accompanying text. At the end, play the game to review the basics of atoms that you have just learned about. You may play the game as many times as...

Students build atoms of elements 1-20. The entire set can be hung from the ceiling in order of the Periodic Table to be referred to throughout the Chemistry class/unit. This is helpful when teaching bonding and patterns of the Periodic...

Get the skinny on the noble gases on the periodic table. Find out why this family is happy, how well they bond, and exactly who is a part of this happy family.

To the left. To the left. The elements in the left column of the period table are alkali metals with the exception of hydrogen. This is a brief overview of the alkali metals, what their family is all about and how well they bond or do...

This website focuses on the common elements. It provides an alphabetical listing of each common element with its symbol, attributes, and location on the periodic table.

This periodic table offers a brief description and an example when you pause the mouse pointer over the element icon. Click the linked periodic abbreviation for detailed information.

This lesson will define molar mass and give examples of elements with different molar masses using the periodic table. It is 1 of 2 in the series titled "Molar Mass of an Element."

This activity is designed to assess the comprehension of concepts related to periodic law.

This site provides elemental information which may not be found in many other sites. Here you can find historical information, common uses and even the approximate going price for a gram of the element.
