What are stable and unstable elements of nuclear chemistry?
Unstable chemical elements are disintegrated by radioactive decay.
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.
How many different elements appear in the decay chain?
There are about 110 elements found in the periodic table.... is it the same as decay chain?
How are isotopes different from stable atoms?
Unstable isotopes can spontaneously undergo changes, transforming them into other isotopes of the same or of different elements. Stable isotopes do not. Some isotopes are very unstable and exist for less than a second; others can exist for billions of years but still be unstable. Many elements consist of more than one isotope. One or more of these isotopes may be unstable. In isotopes of an element, the nucleus contains different numbers of neutrons while the number of protons remains the same and determines how the atom behaves chemically. There are several types of instability (too few neutrons, too many neutrons) and several types of decay.
How long does it take for half of an unstable atom to decay?
It depends on the element. Different elements and isotopes of elements have differing half lives. You need to specify which one you are referring to.
What are stable and unstable elements of nuclear chemistry?
Unstable chemical elements are disintegrated by radioactive decay.
Is it possible the daughter element is parent to other elements and further decay in daughter elements is possible why?
An unstable element may break down into one or more unstable elements, so they can in turn decay. It's possible because there is no reason why it wouldn't be possible, no reason to assume that when something unstable breaks down, all pieces are stable.
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.
What are unstable elements that give off energy as they decay called?
The elements described are said to be radioactive.
Why is decay necessary?
Those elements undergo the 'decay' process which have unstable nuclei so decay is necessary to gain the stability. such elements form the smaller stable nuclei as Lead nucleus.
What are synthesizers?
Synthetic elements are unstable chemical elements not naturally found on the earth. They are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements.
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
What is the property of an unstable isotope?
It will decay to a more stable lighter elements and release out some nuclear energy.
As radioactive uranium decay it turns into what stable element?
Heavy radioactive elements (parent nuclei) decay to form daughter products that are as varied in number as the parents. Each heavy element has its own daughter.To find the decay mode and end products of the radioactive decay for a given isotope, use a Table of Nuclides. A link is provided to the interactive chart posted by the National Nuclear Data Center at the Brookhaven National Laboratory.The final stable element formed by all radioactive decay is lead (element number 82).
When radioactive isotopes break down into other elements the process is called?
radioactive decay
Why are synthetic elements dangerous?
While there are some stable synthetic elements (eg technetium) and also naturally occurring elements which are radioactively unstable (eg radium), synthetic elements are more likely to be radioactively unstable. Their decay process produces radioactive emissions which are hazardous.
