Ionic Bonding
This program uses the idea of filling electron shells to explain the formation of cations and anions. Electrostatic forces are then used to explain lattice formation, and the relationship between properties and structure is examined. Ionic bonding i...
Chemistry: Material World Series - Good Vibrations
This program focuses on the particle theory of matter and how it helps to explain: 1) the behavior of solids, liquids and gases; 2) changes of state; 3) melting points and boiling points, using the example of train tracks to explain expanding metals...
Bonding in Molecules
This program considers the bonds formed when atoms share electrons (covalent bonding). The idea of filling electron shells to reach a more stable state is used to explain the formation of simple molecules such as water and methane. Shapes of molecul...
Chemical reactions
What do fireworks, a fried egg, and a rusting truck have in common? They all involve chemical reactions. This program illustrates the mechanics of chemical reactions in five sections: Chemical Reactions (reactants and products, state changes, diatom...
Bonding in Metals
This program begins with an examination of atomic structure—presented in terms of protons, neutrons, and electrons—and the idea that bonding is related to the filling of electron shells to create more stable particles. Examples of metals and the...
Chemical bonding
"An atom with eight electrons in its valence shell is a happy atom." Section one of this program makes sense of Lewis structures and resonance structures while addressing the Octet Rule and its exceptions. In section two, "Professor Einsteinium" and...
The Nature of Matter
An elephant and a racing car don’t have much in common—except for the remarkable fact that they’re made of similar fundamental building blocks. This program takes a simulated subatomic look at a glass of water to better understand the nature o...
Bonding Between Molecules
In this program, bonding is explained in terms of dipole-dipole bonding for polar molecules, and dispersion forces for both polar and nonpolar molecules. Changes of state for water are examined, and the decreased density of ice when compared with li...
