2.2 Nuclear Reactions (Nuclear Fusion)

Question 1

What is a Nuclear Fusion Reaction?

Answer 1

Two or more light atomic nuclei fuse together to form a single heavier nucleus of a new element; under high temperature and pressure.

Question 2

What are the conditions of the reaction?

Answer 2

High temperature and pressure.

Question 3

Why is high temperature and pressure required?

Answer 3

To overcome the repulsion of the positive charges on the two nuclei.

Question 4

What happens to the two positive nuclei when there is not a high temperature and pressure.

Answer 4

The two positive nuclei repel.

Question 5

Nuclear Reaction Equations RULES (4)

Answer 5

1. Add bottom and top number (mass number + atomic number)
2. MUST for a new element.
3. If the new element formed is formed and the mass number or atomic number is stable and correct then a neutron is needed.
4. If an element appears with a larger number in from multiply top and bottom number.
