Summary: 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 liquid water is explained in terms of intermolecular bonding. Polarity is explained within the context of electronegativity. Formation of...

Summary: 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...

Summary: 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 usefulness are presented, and the relationship between properties and structure is examined. Other processes demonstrated include the formation of...

Summary: 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 molecules are explained by considering the repulsion between molecular orbitals. Further shapes are illustrated using CH4, NH3, and NH4. Double bonds (O2)...
