Nuclear Reactions

1. Using a visual and at least 2 complete sentences, define the two nuclear processes listed below:

Some key words that may be used are: fission, fusion, element, proton, neutron, combine, break apart, energy, exothermic, nuclear force, repulsion

Fission

Fusion

2. Where does the energy released from a hydrogen bomb come from? (Hint: fusion reaction)

Name: HW.

Date: Block:

3. Classify each of the following reactions as either alpha decay, beta decay, nuclear fission or nuclear fusion

Reaction Type of Reaction

a. ____________________

b. ____________________

c. ____________________

d. ____________________

4. In a nuclear fission reaction, which has more mass, the initial uranium (reactant) or one of its products?

5. A pool player starts the game by striking the cue ball (white ball) into the triangle (where the other balls are). The cue ball hits only the ball at the top of the triangle first but they eventually all move, as the first ball collides with the next, and so on.

In 1-2 complete sentences, describe how the collision between the cue ball and the other balls represents a nuclear chain reaction.

Challenge: Why does a neutron make a better nuclear “bullet” than a proton?
