About This Quiz & Worksheet

Predicting the formation, charge, and formula of an ion requires an understanding of the basic characteristics and properties of the atom, and this quiz/worksheet combo will help you explore those basics and test how well you understand them. These practice questions will test you on the formation of ions, identifying the charge of an ion, and the rules that govern ions.

Quiz & Worksheet Goals

In these assessments, you'll be tested on:

  • How ions are formed
  • Defining the charge of an ion given its group
  • Your understanding of anions
  • The octet rule and how it dictates the behavior of atoms

Skills Practiced

  • Reading comprehension - ensure that you draw the most important information on ions from the related lesson
  • Making connections - use your understanding of periodic groups to determine ionic charge
  • Defining key concepts - ensure that you can accurately define an anion

Additional Learning
