Unit 4 Partner Quiz
• Each student must submit their own, unique completed quiz paper
• You may work quietly with your partner ONLY
Natural Transmutation
• Radioactive isotope = Unstable nucleus
• Spontaneously occur—happen on their own
• Alpha, beta, gamma, positron
• Examples:
Artificial Transmutation
• Man-made transmutations
• High energy particles are fired at the reactant
• Two things are combined
– The nucleus being bombarded
– A high-energy particle
What do you notice is different between the natural and artificial?
Natural: Artificial:
Label the following reactions as
either natural or artificial
