Fission Vs. Fusion
Nuclear Reactors
Mixed Bag
100
the process of emitting energy in the form of waves or particles
What is radiation?
100
This emitted particle is a particle of light.
What is a gamma ray?
100
This type of particle is emitted during a fission reaction.
What is a neutron?
100
The uranium is held in these structures.
What is a fuel rod?
100
This is the number of protons in the nucleus, and gives the atom its identity.
What is atomic number?
200
This part of the atom changes in a nuclear reaction.
What is the nucleus?
200
In this reaction, two protons and two neutrons are emitted.
What is an alpha decay?
200
The type of reaction that occurs when more neutrons are produced by splitting an atom than caused the split.
What is a chain reaction?
200
The element that is used in nuclear reactors.
What is uranium?
200
This is what we call two nuclei of the same element that have different mass numbers.
What are isotopes?
300
atoms of the same element, have the same number of protons but a different number of neutrons
What are isotopes?
300
In this reaction, a neutron turns into a proton and an electron is emitted.
What happens in beta decay?
300
The type of reaction occurs in nuclear reactors.
What is fission?
300
This liquid is used to cool the fuel rods.
What is water?
300
This is the element that undergoes fusion in the sun.
What is hydrogen?
400
The number of protons and neutrons in a nucleus
What is mass number
400
the length of time it takes half of the atoms of a sample of radioactive isotope to decay
What is a half-life?
400
This type of reaction occurs in stars.
What is fusion?
400
The heat energy from the nuclear reaction in a reactor goes into producing this.
What is steam?
400
Come to the board and write the beta decay of Xenon-129
What is Xe-129 → e- + Cs-129
500
Nuclei with more protons need more of this force to hold them together.
What is the strong nuclear force?
500
Come to the board and write the equation for this nuclear decay. Neon-22 is formed when an element undergoes a beta decay.
see board
500
Two things that are needed for fusion to occur.
What are high temperatures and pressures?
500
These slow the rate of the fission reaction by absorbing neutrons.
What are control rods?
500
Come to the board and write the alpha decay of Uranium-235.
U-235 → Alpha + Th-231
