How the nucleus decays depends on the particular isotope. Some even decay in more than one way. One possibility is called alpha decay. In alpha decay, the nucleus emits an alpha particle (two protons and two neutrons). Another possibility is beta decay, in which one of the nucleons changes from a neutron to a proton or vice versa and the nucleus will throw out a beta particle. A beta particle can be either an electron or a positron. (To conserve lepton number, the nucleus also emits an electron antineutrino or an electron neutrino at the same time.) A third case is electron capture. In this, one of the inner electrons is absorbed by the nucleus, a proton changes to a neutron, and an electron neutrino is thrown off. Heavy nuclides can undergo spontaneous fission, in which the nucleus splits into two smaller daughter particles with mass numbers of roughly 90-100 and 130-140. Often some spare neutrons are also ejected at the same time. Cluster decay is yet another mode, which happens only for nuclei which also decay via alpha decay. It's similar to alpha decay except the emitted particle is not a helium-4 nucleus but a heavier element. It's distinguished from spontaneous fission by the fact in cluster decay, only certain nuclei are emitted and they're always well under 90 amu. Other rare decay modes are possible: proton emission, neutron emission, double proton emission, double beta decay, double electron capture, double positron emission, and electron capture with positron emission. Most of these names should be self-explanatory.

It is called radioactive decay. This process involves the emission of particles or electromagnetic radiation from the unstable nucleus in order to become a more stable configuration.

Is it true that nuclear radiation comes from the decay of atomic nuclei?
Yes, that is correct. Nuclear radiation is the release of energy from the decay of atomic nuclei, which can take the form of particles (alpha, beta, neutrons) or electromagnetic waves (gamma rays).
What very large nuclei tend to be unstable?
Nuclei with very large atomic numbers, such as those above Z=83, tend to be unstable due to the increasing electrostatic repulsion between protons. This can lead to spontaneous radioactive decay in the form of alpha decay, beta decay, or fission.
When does radioactivite decay occur?
Radioactive decay happens in an unstable isotope of a given element, as the isotope decays radiation is given off. As for when exactly, the decay of a nucleus is spontaneous and random so averages are used, these averages are different for different isotopes, but are measured as the "half life" (the time it takes for half the nucleus to decay).
What is the difference between a simulation and actual radioactive decay?
A simulation is a computer-generated model that mimics real-world processes, such as radioactive decay, using mathematical algorithms. Actual radioactive decay is a natural process where unstable atomic nuclei lose energy by emitting radiation. While simulations provide insight into how radioactive decay works, real decay occurs spontaneously and cannot be controlled or manipulated like in a simulation.
Is radioactive decay the same as organic decay?
No, they are different processes. Radioactive decay is the spontaneous breakdown of unstable atomic nuclei, releasing radiation. Organic decay is the decomposition of organic matter by bacteria and fungi, resulting in the breakdown of complex molecules into simpler compounds.
Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
unstable and eventually transform into a stable form. This process is known as radioactive decay and can result in the mineral changing its chemical composition or structure.
What is nuclei that has unstable decay known as?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Radioactivity is caused due to what?
spontaneous decay of unstable atomic nuclei.
What is the name of the process during which atomic nuclei decay?
D. Radioactivity
Process which unstable nuclei emit radiation is called?
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
Is radioactive decay internal or external?
internal, it is a process occurring inside atomic nuclei.
What is splitting of atomic nuclei?
FISSION. nobody on this website knows the answer..... SHAME
Definition of gamma rays?
Penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei.
Is it true that nuclear radiation comes from the decay of atomic nuclei?
Yes, that is correct. Nuclear radiation is the release of energy from the decay of atomic nuclei, which can take the form of particles (alpha, beta, neutrons) or electromagnetic waves (gamma rays).
What is the radioactive decay of an atom resulting in the decrease in the atomic number with no charge in the atomic mass called?
It is called beta decay. there are two types: 1) posive beta decay in which atomic number decreases. 2) negative beta decay in which atomic number increases.
What has the author Jerry Lewis Pietenpol written?
Jerry Lewis Pietenpol has written: 'Atomic corrections to electric-quadrupole gamma decay by heavy nuclei' -- subject(s): Gamma decay, Heavy nuclei, Spectrum analysis
What very large nuclei tend to be unstable?
Nuclei with very large atomic numbers, such as those above Z=83, tend to be unstable due to the increasing electrostatic repulsion between protons. This can lead to spontaneous radioactive decay in the form of alpha decay, beta decay, or fission.
