4.6 Flashcards
1
Q
nuclear fission
process? in 3 steps
A
splitting,
- large nuclei bombarded with a particle
- split into smaller nuclei and neutrons
- releasing large amounts of energy
2
Q
what does the neutrons released from a bombarded nucleus do?
A
it bombards more of the same element
3
Q
chain reaction
what type of reaction? what is released?
(what will it produce?
A
fission reaction that will continue once initiated, releasing a large amount of heat and energy that’ll produce an atomic explosion
4
Q
what type of reaction is used to create energy in nuclear power plants?
A
fission
5
Q
how is energy produced in nuclear power plants? (process)
A
neutron is absorbed by control rods to slow and control chain reactions
6
Q
Nuclear fusion (what happens) what is released?
A
2 small nuclei combine to form a larger nuclei
large amounts of energy
7
Q
why is nuclear fusion not common?
A
they only occur at 100,000,000 Celsius (They occur continuously in stars/sun)
