The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
Why do large nuclei tend to be radioactive?
Large nuclei tend to be radioactive because they are unstable and have an excess of protons and neutrons, leading to a higher likelihood of undergoing radioactive decay to achieve a more stable configuration.
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
What are the various differences between a stable and an unstable nuclei?
The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.
What is the process in which nuclei lose energy by emitting radiation called?
The process in which nuclei lose energy by emitting radiation is called radioactive decay. This process can involve the emission of alpha particles, beta particles, gamma rays, or other forms of radiation.
What property of a radioactive isotope is the length of time it takes half of the nuclei to decay?
This is called the "half-life" of the isotope.
What is it called when an isotope does not undergo radioactive decay?
When an isotope does not undergo radioactive decay, it is considered stable. Stable isotopes have a balanced ratio of protons and neutrons in their nuclei, which prevents them from emitting radiation over time.
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 is the name of the average time needed for half The nuclei and a sample of radioactive substance to undergo radioactive DS our B radioactive substance to undergo radioactive decay?
The average time needed for half of the nuclei in a sample of a radioactive substance to undergo radioactive decay is called the "half-life." This period is a characteristic property of each radioactive isotope and varies significantly between different substances. During one half-life, the quantity of the radioactive material reduces to half of its original amount.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
Why does radioactive decay happen and what are the factors that influence this process?
Radioactive decay occurs when unstable atomic nuclei release energy in the form of radiation to become more stable. Factors that influence this process include the type of radioactive isotope, the amount of the isotope present, and external factors such as temperature and pressure.

How do you calculate the activity of a radioactive sample?
The activity of a radioactive sample is calculated using the formula: Activity = λ*N, where λ is the decay constant of the isotope and N is the number of radioactive nuclei present in the sample. The unit of activity is becquerel (Bq).
What is an electron emitted from an atom into two nuclei with smaller masses is?
its called an isotope c:
What is the length of time it takes for one half of the nuclei of a radioactive isotope to decay?
It can vary from tiny fractions of a second to several sextillion years.
Can a natural isotope be radioactive?
Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.
