Radioactive isotopes are unstable because they have an imbalance of protons and neutrons in their atomic nuclei. This imbalance causes the nucleus to be energetically unstable, leading to the emission of radiation in the form of alpha or beta particles in order to achieve a more stable configuration.
What else can I help you with?
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.
What are the natural process on which radioactive dating is based?
Radioactive dating is based on the natural process of radioactive decay, whereby unstable isotopes of elements decay into more stable isotopes over time. By measuring the amount of parent and daughter isotopes in a sample, scientists can determine the age of the material. This method is commonly used in geology and archaeology to date rocks and artifacts.
What is the process in which the atomic nuclei of unstable isotopes release fast moving particles and energy?
The process is called radioactive decay, in which unstable isotopes undergo spontaneous disintegration to form more stable elements. During this process, fast-moving particles such as alpha and beta particles are emitted, along with energy in the form of gamma rays.
List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
What makes a nucleus radioactive?
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Isotopes which have unstable nucleus and break down at a constant rate over time?
radioactive isotopes! :)
Why are some isotopes called radioactive?
These isotopes are unstable and emit radiation.
Does americium has stable isotopes?
All the isotopes of americium are radioactive and unstable.
Is O radioactive?
If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
Which isotopes break down and give off radiation?
These are the radioactive unstable isotopes.
What element characteristic does radioactive isotopes have?
These isotopes are unstable and disintegrate emitting radiations.
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.
Which transition metals are radioactive or unstable?
Technetium has no stable isotopes.
How many unstable radioactive isotopes does gold have?
all but one.
Which element in group 16 has unstable isotopes?
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
