PART 1: Metals and Non-Metals  Ionic Compounds (electrons are transferred)
Use the Bohr Rutherford Template provided to model what happens when ionic compounds form.
For each ionic compound:
a. Identify which atom is the metal (loses electrons) and which atom is the non-metal (gains electrons).
b. Make a Bohr- Rutherford model of each atom. Use blue for the metal and pink for the non-metal and
draw these in the space provided (use colour if you want).
c. Using your Bohr-Rutherford models, transfer electrons from the metal to the non-metal to form stable
ions and draw these in the space provided. (You may need to make extra atoms in order to have enough
electrons to make all of your ions stable – if needed, add these to your drawings in part b)
d. Count the number of each atom you used and write the chemical formula for the ionic compound.

2. Use the “atoms” and “bonds” provided to build a model of each combination of elements listed in the
table below. You may have to use more than one atom of each type. You may also need to use the
bendy connectors to make double bonds or triple bonds. Count to make sure that each atom in your
model has the correct number of bonds (make sure there are no “empty holes”!)
3. Count the number of atoms for each element in your model. Write a chemical formula for the
molecule, and then draw a diagram of the model you have built. (Note that some of the chemical
formulas have already been given to you).
