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
