Ionic Bonding and Chemical Reactions Review

Bonding & Reactions Review

1/21/2020

One of my favorite parts about teaching chemistry as part of 9th Grade Physical Science is that all of the topics are all part of a larger story. However, when we are deep into the material for each unit, I expect that many students have a hard time seeing how everything fits into the bigger picture. Because of this, I wanted to help students review for our end of the semester cumulative exam in a way that emphasized the thread connecting the content.

This review is split into 4 parts where each section builds off the answers from the previous one. Since it is important that they are using the right values, I have students complete one page at a time and check their answers with a KEY that I have posted somewhere in the room before advancing to the next part.

Part 1 - Elements, Atoms, and the Periodic Table

For the first six boxes, students must identify the element or polyatomic ion that satisfies the clue presented. Each clue leads students through a review of several concepts about atoms, ions, and elements.

Content Covered

Element Families
Ions / Polyatomic Ions
Energy Levels / Valence Electrons
Protons, Neutrons, and Mass #

Part 2 - Ionic Bonding and Naming Compounds

Matching the elements and polyatomic ions from the patterned boxes in part one, students complete the compound formula and name for the combinations presented.

Content Covered

Balancing ionic charges
Ionic compounds with polyatomic ions
Ionic compounds with multivalent metals

Part 3 - Identifying and Predicting Chemical Reactions

Students match patterned boxes with elements and compounds from parts 1 and 2. Given these reactants, students identify the reaction type, predict the products, and balance the equation

Content Covered

Balancing Equations
Predicting Products
- Double Replacement
- Single Replacement
- Decomposition
Single Replacement Activity Series
Diatomic Elements

Part 4 - Stoichiometry

Using the balanced reactions from part 3, students are asked to complete some stoichiometry conversions. They will need access to a periodic table with molar masses to complete some of the problems.

Content Covered

Stoichiometry
Mole ratios
Volume of a mole of gas at STP
Definition of a mole
Molar Mass
