1/2 life Problems
If an isotope has a half life of 5 days, how many days will it take for 63/64 of the isotope to decay?
35 days
Alpha, Beta, and Gamma
What are the 2 ways that nuclear energy can be made called?
Nuclear fission and Nuclear fusion.
What do you call the structures that create nuclear energy?
Nuclear power plants
What is the white stuff that comes out the top of nuclear power plants?
Steam
An isotope started with 500 g. If it's half-life is 20 days, if 100 days have passed, how many grams are left of the original sample?
15.625 g
Which type of ray can be stopped by simple clothing?
Alpha
Which produces more energy, nuclear fission or fusion?
Fusion
Do nuclear power plants cause more pollution than other energy sources?
No
Can we generate nuclear energy using nuclear fusion on Earth?
No
If an isotope has a half-life of 25 minutes, how much time will it take for 12.5% of the original isotope to remain?
75 minutes OR 1 hour and 15 minutes
When a radioactive ray is created, what happens to the isotope that the ray was created from?
The isotope changes element.
Which one involves the splitting of atoms?
Fission
Do modern day power plants use nuclear fission or fusion to create energy?
Nuclear fission
Does radioactive waste have a short or long half-life?
Long, because it can take 1000s of years for radioactive waste to stop being radioactive.
If only 60 grams of an isotope remain after 900 days, and the isotope has a half life of 100 days, what was the mass of the original sample?
Which type of ray can pass through the most materials?
Gamma
Which one involves the combining of atoms?
Fusion
Which 2 radioactive elements do we use in nuclear power plants?
Plutonium and Uranium
What % of the world's electricity is produced by nuclear power plants?
11%
If 850 minutes has passed, and an isotope has a half life of 50 minutes, and only 1 gram remains, how much mass did the original sample have?
65536 g
How far do alpha rays move after they are created?
only a couple of inches.
Which one starts off with a heavier nucleus and ends with a lighter nuclear, and which one starts with a light nucleus and ends with a heavier nucleus?
Fusion starts with a light nucleus and ends with a heavier one, while fission starts with a heavy nucleus and ends with a lighter one.
How do nuclear power plants generate energy?
The radioactive isotope is heated which is then put into cool water, which creates steam that spins a turbine that generates electricity.
Which countries produce the most nuclear power?
(name 5 and get at least 3 out of the 5 correct)
US, France, China, Russia, and South Korea.
