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.
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.
Why those elements does not emit radiation whose atomic number is less than 82?
Elements with atomic numbers less than 82 do not emit radiation because they do not have unstable nuclei. Radioactive decay occurs when an atom has an unstable nucleus, which may be due to an imbalance of protons and neutrons. Elements with atomic numbers greater than 82 are more likely to have unstable isotopes that can undergo radioactive decay.
Where is unstable nuclei most commonly found?
Unstable nuclei are most commonly found in radioactive materials, such as uranium and radium. These materials emit radiation as the unstable nuclei undergo radioactive decay in an attempt to become more stable.
What are fission fragments?
When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
What is the sorce of radioactivity?
The spontaneous decomposition of unstable atomic nuclei.
Radioactivity is caused due to what?
spontaneous decay of unstable atomic nuclei.
What is nuclei that has unstable decay known as?

What is a process in which atomic nuclei of unstable isotopes release fast-moving particles and energy?
Nuclear decay is the process in which atomic nuclei of unstable isotopes release fast-moving particles, such as alpha or beta particles, along with energy in the form of gamma radiation. This process is also known as radioactive decay and results in the transformation of the unstable isotope into a more stable one.
Can radioactivity be canceled?
No, radioactivity cannot be canceled. Radioactivity is a natural process where unstable atomic nuclei release energy in the form of radiation. While the rate of radioactivity can decrease over time as the unstable nuclei decay, the process itself cannot be canceled.
What are the key differences between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
What causes something to be radioactive?
Atomic nuclei with more than 84 protons or a large neutron-to-proton ratio is unstable. These nuclei will lose alpha-particles (generally reduces the nucleus by 2 protons and 2 neutrons) or beta-particles (generally turns a neutron to a proton) until it becomes stable. This can take billions of years or a fraction of a second, depending on the isotope.
What is the difference between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
How many unstable nuclei exist in nature?
There are many unstable nuclei that exist in nature, but the exact number is difficult to determine due to the sheer variety of radioactive isotopes that can occur. These unstable nuclei can undergo radioactive decay to become more stable over time.
