Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
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).
The Structure of an Atom
By Jill Larson
Students examine atomic structure and the octet rule.
The Formation of Ester Bonds in the Synthesis of Lipids
By Richard Wilkosz
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
Gas Volume vs. Temperature (Charles's Law)
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
Common Types of Oxidation-Reduction Reactions
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
By Kaye Krueger
The learner reads an explanation of all of the elements that comprise a future-state map. A map is shown.
Logic State Signals
By Terry Bartelt
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Logic State Indicators
Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.
Students observe the operation of a tri-state buffer used in digital electronics. A brief quiz completes the activity.

Thank you for this wonderful lesson. Textbooks dont do justice to mathematical processes such as this, because they are not static processes. Please make more of these.
