When a nucleus decays what typically happens to the element?

After an element's nucleus decays, it becomes one or more different elements. The type of decay determines what the new element(s) will be. The type of decay the nucleus of an element will undergo depends on the particular isotope of the particular element in question. For example, alpha decay results in an new element which has 2 less protons and 2 less neutrons (decrease in atomic number of 2 and decrease in mass number of 4). Fission results in an element splitting into two new elements of various sizes, accompanied by the release of other random particles. The two new "daughter" element's masses plus the masses of the other released particles will add up (approximately) to the mass of the original element. There are many other types of decay which produce different decay products.


What are radioactive elements called?

There is not one, but many radioactive elements. Radioactive isotopes, to be more precise - because sometimes, one isotope may be stable, while another isotope of the same element is radioactive. All, or most, elements have radioactive isotopes.


What are the differences between a radioactive element and one that transmutes?

Same thing. A radioactive element decays into either a different element (alpha, and beta decay), a lower energy state of the same element (gamma-ray emission), or sometimes breaks into 2 or more pieces (nuclear fission).


What do mineralogists call an element that occurs naturally in its pure form uncombined with other elements?

Mineralogists call an element that occurs naturally in its pure form uncombined with other elements a native element. These elements are typically found in nature in their pure metallic form, such as gold, silver, and copper.


Is hydrogen stable or unstable?

Hydrogen is considered stable in its most common form, which is a diatomic molecule (H2). However, hydrogen can be reactive and form compounds with other elements, making it potentially unstable in certain chemical reactions.

Is francium a radioactive element?

Francium (Fr) is a natural radioactive element, extremely rare.


Is radon 222 unstable or stable?

Radon-222 is unstable because it is a radioactive isotope with a half-life of about 3.8 days. It decays into other elements through the emission of alpha particles.


How long did element 112 stay stable for?

Element 112, also known as copernicium, is a highly unstable synthetic element. It is so unstable that it rapidly decays into other elements within milliseconds. It does not exist in nature and can only be created in a laboratory.


Is element 115 dangerous?

Element 115, also known as moscovium, is a synthetic element that is highly unstable and rapidly decays into other elements. It is not naturally occurring in nature and its short half-life makes it unlikely to pose a significant danger. However, as with any radioactive material, proper handling and containment are necessary to prevent potential risks.


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.


What happened to the part of the plutonium that is no longer ther?

Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.


What type of energy is released when one element decays into other element?

kinetic energy


What is a synthesized element?

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.


What type of energy is released when one element decays into other elements?

Nuclear energy is released when one element decays into other elements through processes like alpha decay, beta decay, or gamma decay. This energy is generated by the breaking of bonds within the nucleus of the atom.


Does ununoctium combine with any element?

Ununoctium is a synthetic element that is highly unstable and has a very short half-life. Due to its extremely rare occurrence and unstable nature, it is unlikely to form stable compounds with other elements.


What are the dangers of ununoctium?

Ununoctium is a highly unstable and radioactive element that has only been produced in laboratories for very short periods of time. Its radioactivity poses health risks due to potential exposure, and its extreme instability makes it difficult to study its properties in depth. Additionally, ununoctium decays quickly into other elements, further limiting its practical applications.


Why does element marry another element?

Elements react ("marry") other elements to achieve stability. Many elements, especially the more reactive ones, are unstable by nature. For example, sodium and chlorine are very unstable. Hence, they will react if they can to form compounds (in this case, sodium chloride). Compounds are more stable because they have the noble gas configuration (i.e. full valence shell).
