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.
What else can I help you with?
How do you use the periodic table of the elements?
Scientists from all over the world use the periodic table as it is quicker for equations, and its a symbol all of them will know from the Chinese to the Indian, so its an easier way all round.
How has Newcastle changed over time?
because of all the people coming over on boats
Are all elements pure?
No, they can contain impurities.
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
What are the elements in Earth's crust oceans and the atmosphere?
small traces of all elements
Do all elements decay over time?
No, not all elements decay over time. Some elements are stable and do not undergo radioactive decay.
Do all elements have a half-life?
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.
How has americium changed over time?
As all radioactive elements, isotopes of americium continuously decay.
Do all atoms decay over time?
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
What is the name of the elements that have the atomic number over 95?
All these elements are raidoactive, and will decay with the emission of alpha, beata or gamma radiation.
Does all elements undergo nuclear decay?
No.
Why don't man made elements last long?
All elements on the periodic table after lead are unstable, meaning they decay over time. These elements generally become more unstable the further up you go. This is partly due to the fact that the large nuclei hold an enormous amount of energy, which is released by this decay. All elements heavier than iron are forged in exploding stars. However, once you get past uranium, not even a supernova has enough power to create such elements. It is only by concetrating elements and focusing energy that we are able to produce such high-energy elements.
What is stable elements?
Unstable elements are radioactive elements that spontaneously decay into other elements. Some are: Radon Uranium Plutonium See the related link for an article giving greater detail on isotope stability.
Does Pepsi cause tooth decay?
All Sodas can over a long period of time. I would say that coke would cause faster decay than pepsi.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Where all the elements discovered at the same time?
No, elements were not all discovered at the same time. Elements have been discovered over time through various scientific methods such as chemical analysis, experimentation, and observation. The periodic table continues to be updated as new elements are discovered.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
