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...
This program examines the concept of chemical change and the tremendous variety of chemical reactions that go on around us every day. It also looks at some interesting examples of chemical reactions in: 1) space shuttle fuel; 2) explosions; 3) firew...
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...
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...
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...
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...
This program further explores the idea that everything is made of particles by looking at: 1) the difference between atoms and molecules; 2) the difference between elements, compounds and mixtures; 3) how an element like lead can exist in various fo...
