Fill-in-the-blanks Exercises

This program is capable of generating a large number of exercises. It selects isotopes at random, decides on which information to supply and which to require you to provide. It will also decide, at random, whether or not an isotopic ion will be given. A typical exercise might ask you to find the element symbol, the atomic number, the mass number, number of protons, number of neutrons and/or the charge on the ion. You can try out the program by using the demo version that you will see further down in this page. A link to the page for the other program in this module is included below. Just click on the graphic for the 'Isotopes Symbols' program ... About the buttons you will see in the program window ...
