Nuclear Process
Fusson
By David.C
Nuclear Fussion
Occurs when two small nuclei collide, this process release the most energy compare to all other methods we know now, while in order for it to occur we need very high pressure and high temperature, our sun is an example of fusion decay and his process does not need neutrons in order to occur
Nuclear Fission
Fission
Occurs when large, unstable atoms are split in half., as they split in half they always released high energy particlues which will hit another atom which will causing the atom that got hit to split into half also and release high energy which creates a chain reaction.
Usually, the high-energy particle that escaped is a helium particle which is basically alpha decay.
Alpha Decay
Alpha
Occurs when an atomic nucleus emits an alpha particle. Usally occur to the elements that has a mass higher than 82(lead) because those element's aren't really stable therefore they decay themselves which makes them more stable, and can be blocked by hands, clothes, or a sheet of paper. Alpha emission is
Beta Decay
Beta
Occur when an atom have too much proton or neutron.
Whenever it occurs it change one proton or neutron to the other by adding or emiting a electron, since both of them as the mass of one and the electron have almost the mass of zero therefore when an beta decay occur the mass stays the same, and can be blocked by a piece of metal
Electron Capture
Electron Capture
(Negative beta)
When there's more neutron in an atom a Negative Beta decay occur(Also know as Electron Capture)
Where a neutron transfers into a proton by emitting an electron from the neutron.
Positron Emission
(Positive beta)
Positron Emission
Occurs when there's more proton than neutron, where a proton transfer into a neutron by adding an electron to the proton and then they become a neutron.
Gamma Decay
Gamma
Gamma rays are made of high energy photons. Gamma are created under anytype of nuclear reactions. They are emited during the process. For example during an alpha decay of U-238, 2 additional gamma rays are emitted addition to the alpha particle, and can be blocked by thick, lead, shield, or concrete block.
Nuclear Proccess vs Chemical Proccess.
As you might noticed the energy produced during the nuclear process(Fussion, Fission, Alpha) has a much bigger scale compare to chemical proccess(Beta, Gamma)
Nuclear Process
vs
Chemical Process
As we can see from the image in a nuclear proccess there are more atoms involved compare to chemical proccess therefore it creates more energy. While on the other hand chemical reaction are reaction that happen to the atom itself while nuclear processes affacts the atoms around it also.
