PS1-8.2 Fission and Fusion Review

​PS1-8.1 Fission and Fusion Review

​PS1-8.2: I can develop a model of radioactive decay that includes the identification of all atoms and particles and their relationships, and transformations of energy with the proper number of subatomic particles both before and after decay (fission and fusion).

Multiple Choice

What is the process of fusion?

• When an atom breaks apart into smaller ones

• When two atoms come together and form a bigger one

• When a lot of energy gets released like inside the sun

• A type of nuclear decay

Multiple Choice

What is the process of fission?

• Two atoms coming together to make a bigger new element

• An atom breaking apart into multiple smaller atoms

• Gives off a lot of energy like in nuclear reactors

• A way to build new atoms
