Ionic Bonding Puzzle Lab
Introduction
When metals and non-metals chemically react, the atoms will tend to form ions or charged atoms. Ions form because electrons are either gained or lost. Metals will generally form cations or positive ions, since they tend to donate electrons Non-metals will form anions or negative ions, since they tend to accept electrons.
Activity
In this activity you will create models of ionic compounds and observe the chemical formula of the binary molecules you have created. Your data will be recorded in a data table or chart, similar to the one below.
Cation name
Anion name
Chemical Formula
Name
Discussion/Conclusion (talk with your classmates and address in your write-up)
Notice the shape and charge of each cation model. Why do you think there are slots in the metal atoms? (TIP: How do the atoms become ions?)
Notice the shape and charge of the anion models. Why do you think there are tabs in the non-metal atoms?
If you were to make a neutral atom following the model, what would the shape be?
Group the ion models by family. What do you notice about the number of tabs or slots? What do you notice about the tabs or slots and charge of all ions? Is there a pattern? Why do you think the model is made that way?
In the compounds you formed, what do you notice about the ion charges, the net or final charge of the compound and how the charge relates to the chemical formula of the compound?
What do you notice about the names of the cations and anions on the cards. How do they compare with the name of the neutral atom or element. Do all metals have a number in parenthesis? Do the non-metals have anything in common about their name?
Is there a pattern between elements in a group or family and any numbers on the Periodic Table? (TIP: Think octet rule and how many electrons are involved to meet octet.)
