Metals and Non-Metals - Ionic Compounds
Use the Bohr-Rutherford templates 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 diagrams in the space provided (use colour!).
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 the ions stable – if necessary add these to your drawings in
part b)
d. Count the number of each atom used and write the chemical formula for the ionic compound.

Non-Metals and Non-Metals – Molecules
1. Complete the table for the following atoms
Hydrogen
Carbon
2. Use the “atoms” and “bonds” provided to build a model of each combination of elements listed in
the table on the back of this page. You may have to use more than one atom of each type.
Count to make sure that each atom in your model contains the correct number of bonds.
3. Count the number of atoms for each element in your model. Write a chemical formula for the
molecule in the corresponding column of your table.
4. Draw a diagram of the model you have built in the corresponding column of your table.
