Nuclear Fission And Fussion Flashcards
What is nuclear fusion?
The joining of to atomic nuclei
What is realised during both nuclear fission and nuclear fusion?
Energy/Gamma (radiation)
Name 2 substances used as a fuel for nuclear reactors
Plutonium (-239) uranium (-235)
What is nuclear fission?
The splitting of a large atomic nucleus
What dose the nuclei of different plutonium isotopes have in common?
Sam number of protons,atomic number,positive charge
What is the process of nuclear fusion?
Two nuclei/hydrogen atoms join tougher
Where dose nuclear fusion happen naturally?
In stars

Where dose nuclear fusion happen naturally?
In stars
For nuclear fission to accrue what most uranium and plutonium nucleus first absorb?
Neutrons
What dose the energy produced from nuclear fusion allow to happen to produce electricity?
It releases energy which can be used to heat water and turn into steam. The steam drives a turbine which is connected to a generator and generates electricity.
What dose the energy from nuclear fission use for?
A process which energy is realised in stars
How are stars stable?
Because of the forces in it are unbalanced
How is a star formed?
A nebula of gas and dust build up. The matter then forms a core (center circle). The matter becomes hot and dense that fusion starts making is shine brightly for many years.
