Ionic Bonding Practice
Directions:
Define the terms below and then fill in the tables below.
1. Neutral atom:
2. Ion:
3. Proton:
4. Electron:
5. Ionic Bond:
Use the periodic table to determine how many electrons each element will gain or lose.
Draw the Electron Dot Diagram of each element and use an arrow to show how the electrons
move from one element to the next. Write the formula of the ionic compound that is formed.
Remember, that the overall charge of ionic compounds is neutral.

Directions:
Use the information in the data tables to answer the following questions. Answers must be
written in complete sentences.
1. What do all of the elements that form positive ions have in common? (Remember: to form a
positive ion an atom must lose electrons)
2. What do all of the elements that form negative ions have in common? (Remember: to form a
negative ion an atom must gain electrons)
3. Is there a relationship between the group number and the number of valence electrons in an
atom? If yes, describe that relationship.

5. What is the overall charge of an ionic compound? In other words, what is the sum of the
charges of each ion in an ionic compound?
