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.
Is 288 is unstable or reactive atom?
The number 288 does not correspond to an atom as it is not a specific element. Atoms themselves are not considered stable or unstable, but certain isotopes of elements can be unstable and undergo radioactive decay.
Why does the decay chain stop at lead-206?
Lead-206 is a stable isotope, which means it does not undergo further radioactive decay. As a result, the decay chain stops at lead-206 because it does not have any unstable isotopes that it can decay into.
Why does radioactive decay happen?
Radioactive decay happens because unstable atomic nuclei release energy in the form of radiation to become more stable.
Are most isotopes stable?
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
What is stable and unstable isotopes?
Some isotopes are stable, others are unstable.
When does an unstable isotope break down into a stable isotope?
The process is called decay, or sometimes nuclear decay. A link can be found below.
Are daughter isotopes always stable?
No. Often a decay product is itself unstable and will decay into something else until a stable isotope is reached. This is called a decay chain. For example, Uranium-238 will decay 15 times through various isotopes until it becomes lead-206 which is stable

What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
Which isotopes are most likely to decay?
Isotopes with a high atomic number and/or an unstable ratio of protons to neutrons are more likely to decay. Generally, isotopes further from the line of stability on the periodic table are more likely to undergo radioactive decay.
Do all elements decay over time?
It is the unstable isotopes of elements that decay over time. All elements have an isotope or isotopes that are unstable and will decay over time. (These isotopes will be either naturally occurring or will be synthetic.) Some isotopes of some elements, however, are stable, and they will not undergo radioactive decay.To discover what's what, we have to do some homework, and what better place to start than the table of nuclides? It lists all the elemets, and all the isotopes of each element. Further, it tells us which ones are stable, which are unstable, and will also help us determine the decay mode of the unstable nuclides.
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
Why synthesized isotopes emit alpha and beta particles?
All radioactive isotopes are unstable and they decay to a stable isotope emitting particles.
Is the decay of unstable isotopes always the same process?
Yes, for the specified isotope; but the process is statistic.
Where does decay and radiation occur?
Decay and radiation occur at the atomic level within unstable nuclei of atoms. Decay is the process where an unstable nucleus emits particles or energy to become more stable, while radiation refers to the particles or energy emitted during this process. Both decay and radiation can occur in natural radioactive elements or in artificially created radioactive isotopes.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
