Which type of radioactive decay is represented by the reaction pictured?

• Alpha Decay, the atomic nucleus emits energy that changes the atom and the mass number is decreased by 4 while the atomic number is decreased by 2

• Beta Decay, the neutron is split into a proton and electron within the nucleus while keeping the mass number the same and increases the atomic number by 1

• Gamma Decay, the nucleus emits a photon of light releasing energy while the mass number and atomic number stays the same

• Nuclear Decay, the nucleus is affected by a collision between the neutrons and the protons that caused the mass number to decrease to 0 and the atomic number increase by 2

Tim creates a model of a fission reaction using plastic building blocks. He uses four black blocks for to represent neutrons. He uses a red block for barium and a blue block for krypton. For uranium-235, he snaps two black, one red, and one blue block together.

The half-life of uranium-235 is 700 million years. If there are 2000 g of uranium-235 in the original sample, what happens after 2100 million years have passed? Select all that apply.

• One half-life has passed.

• Two half-lives have passed.

• Three half-lives have passed.

• 125 g of the original sample remains.

The graph shows the range of amounts of carbon dioxide (CO2) given off to produce one kilowatt/hour for different methods of electricity production.

How does the amount of carbon dioxide given off by nuclear power compare with the amount of carbon dioxide produced by solar photovoltaic?

• Nuclear power produces half as much CO2 as solar photovoltaic power.

• Nuclear power produces more CO2 than solar photovoltaic power.

• Nuclear power produces less than 10% of the CO2 produced by solar photovoltaic power.

• Solar photovoltaic power produces less CO2 than nuclear power.

How are fusion and fission alike?

• Both combines small nuclei into a large nuclei.

• Both break large nuclei into smaller nuclei.

• Both produce large amounts of energy.

• Both produce large amounts of matter from a small amount of matter.
