Chem-Words 2: Atoms, Molecules and Ions

Covers 27 HS/College Chem terms about atoms, molecules, and ions.

This FREEWARE application covers the introductory topics 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 the 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 registration. There are no ads or permissions and the internet is not needed. It should not be sold for profit.
