Six challenges are included with the program; they help you test your knowledge of symbols for different chemical elements and ions, the electron configuration of the elements, balancing chemical equations, etc.
To answer the questions all you have to do is enter the values for the formula, or select the correct chemical compound from the scroll down menu.
Alchemist's Challenge does not include a periodic table on which to find the different elements, but it does have a list with the name and formula for ions, acids, and covalent compounds.
For Mac OS X 10.3 or above.
Only two tests are available on this trial version.
