Nuclear Power (Fission and Fusion)

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

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

What occurs in both fusion and fission reactions?

• Small amounts of energy are converted into large amounts of matter.

• Small amounts of matter are converted into large amounts of energy.

• Heavy nuclei are split into lighter nuclei.

• Light nuclei are combined into heavier nuclei.

What is one benefit associated with a nuclear fission reaction?

• The products are not radioactive.

• Stable isotopes are used as reactants.

• There is no chance of biological exposure.

• A large amount of energy is produced.

Nuclear fusion differs from nucleus fission because nucleus fusion reactions

• form heavier isotopes from lighter isotopes

• form lighter isotopes from heavier isotopes

• convert mass to energy

• convert energy to mass
