Nuclear Chemistry
A self-sustaining series of nuclear reactions is called this.
What is a Chain Reaction.
What term describes the process where an unstable nucleus spontaneously emits particles or energy to become more stable
What is radioactive decay?
What is the process where a heavy atomic nucleus splits into two or more smaller nuclei?
What is fission?
This radiation type can be stopped by aluminum.
What is a beta particle.
What is the type of nuclear reaction that occurs on the sun?
What is fusion
What process releases energy when small atomic nuclei combine to form a larger nuclei?
What is fusion?
A greater mass defect when a nucleus forms leads to this.
What is a greater release of nuclear binding or more stable isotope.
Alpha decay of Polonium-218 yields this isotope
What is Lead-214
What term describes the time it takes for half of a radioactive nuclei to decay?
What is half-life
Which radiation type has the ability to penetrate deeply into materials
What device is used to measure or detect radiation in the environment or objects?
What is a Geiger counter?
This radiation type can be stopped by paper
What is alpha radiation?
Krypton-85 has half-life equal to 11 years. How much remains of a 2.000 mg sample after 33 years?
What is 0.250 mg?
Which type of radioactive decay involves the emission of an electron from the nucleus?
Beta decay of Mercury-210 yields this isotope.
Thallium-210
Alpha decay of Plutonium-240 yields this isotope.
what is Uranium-236
What is Lung Cancer?
The decay of a radionuclide with a half-life of 6.0 hours has a rate constant (in hours^-1) equal to this.
What is 0.12
Phosphorous-30 decays to Silicon-30 with this process.
What is positron decay/emission
This isotope is usesful for radiometric dating
