  • What is the name of the process in which two small nuclei are joined to produce one larger nucleus and lots of energy?
    fusion
  • to put forth and idea for consideration
    propose
  • Data that is in numbers or measurements
    quantitative
  • Most of the world's electricity is made using fossil fuels as an energy source. In what way is nuclear fission a better alternative to fossil fuels?
    Less air pollution, provides clean energy and is reliable and cost effective
  • Can be stopped by a sheet of metal
    beta
  • We have a 2 gram sample of a radioactive sample. How much would remain radioactive after 2 half lives?
    0.5 g
  • not normal
    irregular
  • Data in the form of recorded descriptions rather than numerical measurements.
    qualitative
  • to put into a different language or form
    translate
  • Takes place inside the sun
    fusion
  • Can be used in medical treatment ( there are 2)
    beta and gamma
  • Produces a nucleus with higher atomic number but same mass number
    Beta
  • made up of 2 protons and 2 neutrons
    alpha
  • Made of high energy waves
    gamma
  • an organized method of doing something
    system
  • Used in nuclear power plants
    fission
  • Can be stopped by a sheet of paper
    alpha
  • Releases more energy than the other
    fusion
  • Produces a larger atomic number
    fusion
  • the time required for the amount of radioactivity to decrease by one half
    half life
  • Produces radioactive waste
    fission
  • Used to make atomic bombs
    fusion and fission
  • Created when a neutron breaks into a proton and an electron: proton stays in nucleus
    beta
  • focus of a study
    scope
  • Must be stopped by thick concrete or lead
    gamma
