Atomic Structure: The Heart of Matter

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

How are atoms structured? Viewers of the video first learn about atoms and atomic structure, including the nucleus and electron shells. The video then describes how atomic numbers and atomic masses are expressed on atomic symbols. You'll...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

This site provides an overview of elements and atoms, the building blocks of matter.

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

"The name is Bond. James Bond." Or is that "Chemical Bond?" Assign the viewing of the video as homework, and then have your chemists come to class to practice drawing electron dot diagrams and Lewis structures with the several bonus...

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

This page is an exercise in relating the number of protons, electrons, and neutrons for an atom or monoatomic ion.

This interactive tutorial begins with an understanding of the structure of matter. Understanding charge as a fundamental quantity demands that we have an understanding of the structure of an atom. Learn the atomic structure of an atom an...
