This page from the Department of Chemistry at Washington University provides attractive Lewis dot diagrams and three-dimensional models for many of the common polyatomic ions. The images will make your visit worthwhile.

Four interactive tutorials begin with a basic animation showing the relationship between positive and negative charges. The final test is to build the most efficient ion engine possible by manipulating a series of variables.

This site includes a list of the names, formulas, and charges of some common polyatomic ions.

Learn how to name monatomic ions and ionic compounds containing monatomic ions, predict charges for monatomic ions, and understand formulas.

In this classroom activity students will utilize the familiar matching game concept they played as youth to match elements and their symbols, ionic ions into formulas, and learn common ion charges of the most well known elements.

This site is an encyclopedia article from the Wikipedia Encyclopedia on Ion. Throughout the site, links are provided for additional information. The information is somewhat in-depth, but also very factual and interesting.

Common polyatomic ions are listed in a table. Includes chemical symbol, charge, and oxidation number.

This brief entry describes the hydrogen ion, strictly, as the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton.

Student groups explore propulsion technology necessary for the Dawn project to complete its mission. Learning module components include story mapping, online interactive activity, RAFT writing exercise, and other standards-aligned...

The page from NASA's The Space Place describes a simple activity, charging a balloon and making it move small pieces of paper. It then goes on to give an excellent explanation of how the activity works, and how it involves ions. This...

This page links to a number of Java games that are designed to make learning the names, symbols and charges of the various cations fun.

At this site from Fernbank you can become a pro by practicing them with this review game.

This web-based activity takes students through a series of pages in which they find out about the effects charged particles have on one another, discover how Coulomb's force works, and see some real-world examples. Multiple-choice and...

[Free Registration/Login Required] In this simulation, students look at the question of whether one can score a goal in an electric field. They experiment with positive and negative charges to try to score goals.

NASA's Glenn Research Center reports on its innovative engines program, namely ion propulsion, a technology that once only powered imaginary spacecraft in science fiction novels. It is now a reality.
