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.


What does being radioactive mean?

Exhibiting or caused by radioactivity.Radioactivity: the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay.Examples are radioactive isotopes [an unstable nucleus that undergoes radioactive decay], radioactive dating [the process by which the approximate age of an object is determined based on the amount of certain radioactive nuclides present], and radioactive decay [the spontaneous disintegration of a nucleus into a slightly lighter and more stable nucleus, accompanied by emission of particles, electromagnetic radiation, or both.]


How does radiation dissipate?

When the Sun's heat warms the ground and air.


Are superheavy elements stable or unstable?

Superheavy elements are generally very unstable and quickly decay through nuclear processes like alpha decay or spontaneous fission. Their short half-lives make them difficult to study and understand.


What are radioactivity?

Radioactivity was discovered by Henry Becquerel but the term 'Radioactivity' was given by Madam Curie. It is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter.


When a mineral decays into subatomic particles?

Radioactive decay is the process through which unstable atoms disintegrate and emit radiation until they attain a stable configuration. New elements with reduced atomic number are formed.


Will unstable nuclei all undergo radioactive decay in order to gain stability?

Not necessarily. Some unstable nuclei can gain stability through processes such as alpha or beta decay, while others can undergo spontaneous fission. Additionally, some unstable nuclei may be in a metastable state and decay through isomeric transition.


Heat Travels from the sun to the earth by means of a process called?

Heat travels from the sun to the Earth through a process called radiation. Radiation is the transfer of heat energy through electromagnetic waves such as light.


Isotopes with unstable nuclei are?

Isotopes with unstable nuclei are radioactive and can undergo radioactive decay to achieve a more stable state. This decay process involves the release of radiation such as alpha or beta particles. The unstable isotopes are often used in various applications, including medicine and energy production.


How is heat trans fered from the sun to the earth?

Through the process of radiation.


What do radiation do?

During radiation, energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process.


Can entropy decrease during a process?

in general entropy will not decrease in a spontaneous process since spontaneous process are all irreversible ones. entropy can be reversed only through an reversible process by an ideal engine but it is impossible to create such an engine by violating second law of thermodynamics. hence entropy cannot be decreased practically
