Nuclear Chemistry Flashcards
Alpha particles
Are positively charged
Radioactive materials have unstable
Nuclei
Which of the following is not a type of nuclear radiation?
X rays
Nuclear radiation refers to charged particles or energy emitted by an unstable
Nucleus
Alpha particles are nuclei of
Helium
During bata decay, a nucleus
Gains a proton and loses a neutron
In radioactive decay, with each successive half-life, half the remaining sample decays to from another
Element
Nuclei with too many or too few neutrons are
Unstable
Fusion occurs when nuclei
Combine
The opposite reaction to fusion is called
Fission
In the equation E=mc2, ācā stands for
The speed of light
You prepare a large screened-in box, inside which you place several dozen mouse traps. You set each trap and on each trap your place a ping pong ball. You then drop another ping pong ball into the box, which sets off one mouse trap, which sets of another mouse trap, and so on. You have just demonstrated
A chain reaction
Radon gas is produced
Through radioactive decay of uranium-238 in Earths crust
Small radioactive sources that are present in smoke detectors release
Alpha partials
Short-lived isotopes used in agriculture to monitor water flow through crops are called
Radioactive tracers
