|
Strong Force |
force that causes protons and neutrons to be attracted to each other |
|
|
Radioactivity |
nucleus decays and gives off matter |
|
|
Alpha Particle |
made of two protons and two neutrons and is emitted from the decaying nucleus |
|
|
Transmutation |
changing one element to another through nuclear decay |
|
|
Beta Particle |
neutron decays into a proton and emits an electron |
|
|
Gamma Rays |
electromagnetic waves with the highest frequencies and shortest wavelength no mass and no charge travel at the speed of light |
|
|
Half-life |
amount of time it takes for half the nucleus in a sample of the isotope to decay |
|
|
Cloud Chamber |
used to detect alpha or beta particle radiation |
|
|
Bubble Chamber |
holds super-heated liquid with does not boil because the pressure in the chamber is high |
|
|
Geiger Counter |
device that measures the amount of radiation by producing an electric current when it detects a charged particle |
|
|
Nuclear Fission |
the process of splitting a nucleus into several smaller nuclei |
|
|
Chain Reaction |
series of repeated fission reactions caused by the release of neutrons in each reaction |
|
|
Critical Mass |
the amount of material required so that each fission reaction produces approximately one more fission reaction |
|
|
Nuclear Fission |
two nuclei with low masses are combined to form one nucleus of larger mass |
|
|
Tracer |
A radioisotope is used to find or keep track of molecules in an organism |
