Nuclear Fission vs Nuclear Fusion
2
Nuclear Fission
a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
a neutron bombards the target nucleus which sets off a chain reaction

4
Nuclear Weapons
Atomic Bombs use uncontrolled fission reactions
Thermonuclear (hydrogen) bombs use fission reactions to induce fusion - 100x more powerful than atomic bombs
5
Nuclear Power Plants
Reactors with controlled U-235 fission reactions
These reactions produce heat & steam, which spins turbines that generate electricity.
A very small amount of U-235 can produce the same amount of energy as a very large amount of coal (fossil fuel!) & no CO2 is produced.
There is a limited supply of U-235 & fission produces radioactive waste.
6
Fusion
a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
the difference in mass between the reactants and products is manifested as the release or absorption of energy.
7
The Sun
a massive ball of plasma.
It is constantly burning so hot that hydrogen is fused together to form helium.
This happens at such a rate that a huge amount of energy is released.
