Everythingin the universeis either matter or energy. All matter is made of combinations of about one hundred basic building blocks, the chemical elements on the periodic table. Going a step further and breaking these elements down to...

As part of the introduction to the Periodic Table of the Elements, students will be introduced to the idea of atoms, molecules, and chemical reactions.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

This page displays the Periodic Table of Elements and allows you to click each individual element for a page that displays in-depth information about that particular element. There are also links to many different games and learning...

ChemCenter, available from the American Chemical Society, provides chemistry news, reference sources and other public services.

This lesson focuses on atoms and elements including what they are, the chemical symbols for elements, and the placement of elements on the periodic table. A link to a test is provided.

How much do you know about the chemical elements? This game will challenge you with questions about chemical symbols, names and atomic numbers.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorail students will learn how to express the arrangement of electrons in atoms through electron configurations and Lewis valence electron...

This interactive periodic table of elements allows students to click on each element, and read essential information about that element. Chemical elements are also listed alphabetically for quick reference.

[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...

Students explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...

[Free Registration/Login Required] Discover the composition of matter and the relationship between matter, atoms, and elements. Students will learn the differences between elements and compounds, and how molecules are formed. Chemical...

Wikipedia provides the definition of the term, "Atomic number," a term used in chemistry and physics to represent the number of protons in the nucleus of an atom.

1HNMR theory begins in the nucleus of hydrogen. Complete this tutorial on the 1HNMR spectrum graph to learn about the number of equivalent hydrogens, b) the chemical environment of each hydrogen type and c) the number of neighbouring...

Created to teach students of the 21st century, SOPHIA is bringing matter straight to your fingertips. Become the commander of your own learning experiences as you take part in this interactive tutorial. [1:02]

Through this reading, students will learn that a substance's properties arise from its molecular structure, not from how it's made (i.e., synthesized by people or found in nature). There is no fundamental difference between natural and...

This lesson explains what is represented by the atomic mass, and how it varies from one element to the next. Module includes a slideshow and a quiz.
