In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
Naming Binary Ionic Compounds Containing Fixed Oxidation State Cations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine a table containing the names of common cations and anions. They then check their knowledge by answering a series of questions.
Electromagnetic Radiation (Screencast)
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Percent Composition of Compounds
Learners examine the method used to calculate the mass percent of an element in a compound. Three examples and one problem illustrate the method.
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
