10 Chemistry – Atoms

This term in Year 10 Chemistry we are studying atoms and how they behave. We conducted an experiment where we tested solutions for different metal ions by heating them. This is called a flame test for atoms. Different atoms will change the colour of the flame when they burn, for example, potassium will burn with a lavender coloured flame, while copper will make the flame go green. This is the basis of the different colours we see in fireworks.
