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 is introduced by comparing the malleability of silver with the brittleness of rock salt. Demonstrations include the formation of sodium and chloride ions from their respective atoms. Lattice formation is explained in terms of electrostatic repulsion and attraction. Models of different lattice structures are illustrated and explained in terms of the relative sizes of ions.

Periodic Table
View Video Clip
The millions of different substances that make up the world can be reduced to a comparatively small number of chemical elements. These, arranged in order of their atomic number, form the Periodic Table. This program from the BBC archives provides a c...(more details)
 
Atoms and Molecules
View Video Clip
In this concise and logically formatted program, students discover the fundamental building blocks of the universe: the elements. Lively computer animation makes the atom and its constituent parts-the proton, neutron, and electron-easy to understand....(more details)
 
Bonding in Molecules
View Video Clip
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 molecule...(more details)
 
Bonding Between Molecules
View Video Clip
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 liq...(more details)
 
Bonding in Metals
View Video Clip
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 their us...(more details)
