Become thorium-234 after ejecting an alpha particle and gamma ray.
The thorium-234 continues to decay through 13 more decay events, ultimately becoming lead-126.
Beta Particle
Copper-67 undergoes beta decay with a halflife of 59 hours, becoming stable Zinc-67.
nothing, the nucleus just relaxes to a lower energy state that is more stable
Yes, it is. Nuclear decay is a process that an unstable atom goes through to lose energy and move toward a more stable state. (It may take more than one decay.) In nuclear decay, the nucleus undergoes a change by releasing a particle or particles and electromagnetic energy. Links are provided to related Wikipedia articles and related questions.
One of the advantages of the nuclear reactors is that they do not produce smoke particles that pollute the environment and therefore lead to the acidic rainfall. The other advantage is that it is easier to control the output of a nuclear reactor to fit a given need. One of the disadvantage of the nuclear reactors is that the disposal of the nuclear waste is very expensive.
When an element undergoes nuclear transmutation the result is a completely different element or isotope. All transmutation occurs through decay or nuclear reaction.
the sun
When the star no longer undergoes nuclear fusion.
Beta Particle
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
Nuclear energy is released when U-235 undergoes fission, and that takes place in nuclear reactors (or nuclear weapons). So a reactor is a thing constructed to produce nuclear energy.
the reactor vessel
Star
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
If an atom undergoes a reaction and attains a more stable form, you know if the reaction was a chemical reaction or a nuclear reaction by studying what exactly happened to the atom.
Mainly hydrogen and some helium. The helium is created when the hydrogen undergoes nuclear fusion.
Hydrogen undergoes nuclear fusion to form helium at a temperature of 107 K
