Radioactive
Unstable chemical elements are disintegrated by radioactive decay.
The process is called decay, or sometimes nuclear decay. A link can be found below.
There are about 110 elements found in the periodic table.... is it the same as decay chain?
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.
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.
Unstable chemical elements are disintegrated by radioactive decay.
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.
The process is called decay, or sometimes nuclear decay. A link can be found below.
The elements described are said to be radioactive.
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.
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.
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.
It means that massive nuclei break apart.
It will decay to a more stable lighter elements and release out some nuclear energy.
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).
radioactive decay
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.
