Chem-Words 2: Atoms, Molecules, and Ions

This FREEWARE Android application covers topics about atoms, molecules, and ions and included in most Chemistry textbooks.  The terms used in this app are based on the free chemistry e-book from OpenStax.org.  There are 27 terms presented in 2 sets.  Topics covered include atomic structure, isotopes, formulas, isomers, and ions.  The user must select the term that matches a given  definition. Each word set has a Study Screen for the user to read and review the information.

The score is reported as an accuracy of the number of correct answers out of the total answers selected.  A “help” button reveals the answer, if needed.
This app works fine with Android versions 5.0 through 9.0. This app is offered totally free of charge and does not require a registration. There are no ads or permissions and the internet is not needed.  It should not be sold for profit. Send questions and comments to Richard Carman at rtcarman47@ gmail.com
