Atoms, Ions, Stability and Numbers STUDY GUIDE!

Atoms, Ions, Numbers, and Stability Test

HINT SHEET

This exam will be the largest test you have taken in chemistry so far.  At this time, there are 40 multiple choice questions and 8 free response.  Questions are similar to those from recent worksheets and class activities.  Note:  There is no unit factoring on this exam.  It is all content.
