The Story of the Atom

Bold boxes present parts of the periodic table, with some of the contents conveniently missing. Beginning chemists fill in the blanks, which may include the atomic number, atomic mass, atomic symbol, or element name. Beneath each box...

Learners see how electrons are transferred in the bonding of NaCl. They then create models of NaCl using styrofoam balls and toothpicks to assist them in explaining the formation of ions and ionic bonding. 

This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...

What's the best way to draw an atom? Well, that depends on what information you need to convey. Compare and contrast the atomic models of Bohr, Rutherford, and Lewis using a video from the JFR Science series. The resource shows the basis...

A more detailed description and definition of orbitals, and the role they play in the atomic world are the focus of this video. The "P Orbitals" are described by taking a close look at the carbon element's properties. The periodic table...

Elements don't have fingers, but they have fingerprints! An interactive simulation gives young scientists the opportunity to study orbital changes of an atom and the corresponding spectrum reading. They realize how each atom has a...

What does an atom look like? The instructor in a tutorial video models how to use the periodic table to determine the number of subatomic particles. He then uses the number of electrons to create an orbital diagram. Finally, Groves...

A well designed clear tutorial explaining the energies involved in the Bohr model of the atom. Illustrations add to the clearly presented equations.
