What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
The parent element 247 95 Am decays by beta decay Which daughter element will form?
42 20 Ca
How many decay events can an atom undergo while remaining the same element?
An atom can undergo an infinite number of decay events while remaining the same element as long as it does not change its atomic number. For example, isotopes of an element can undergo decay processes like alpha or beta decay, yet still be classified as the same element if they retain the same number of protons. However, once the atomic number changes through decay, the atom transforms into a different element.
If seaborgium undergoes alpha decay which element is created?
If seaborgium undergoes alpha decay, it would create rutherfordium as the resulting element.
What is the breakdown of a radioactive isotope of the same element or of another element?
radioactive decay
What is one of the daughter elements of urainium-238?
U238 is a stable isotope of uranium - it doesn't undergo decay except at a very very slow rate unless hit with Neutrons - then it will decay to Neptunium
How many neutrons are in Element 92?
Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons
What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
Is half life the same for each isotope?
No, the half-life of each isotope can vary significantly. Different isotopes have different rates at which they decay into other elements. Some isotopes have half-lives of seconds, while others have half-lives of millions of years.
What kind of decay can change one element to another kind of element?
That would be radioactive decay.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
What element does actinium decay into?
Actinium-227 decay to francium-223.
How are isotopes of the same element named?
The same name with a different atomic mass number. As an example U235 and U238 are two isotopes of Uranium
Some atoms such as carbon-14 whose nuclei are not stable lose parts of their nucleus through decay -In the process they become another element -Atoms such as this are said to be?
Atoms with nuclei that are not stable and lose parts through decay are said to be radioactive. This process results in the transformation of the atom into another element, along with the release of energy in the form of radiation.
In alpha and beta decay the parent elements is always a different element from the daughter element?
true
What is the kind of decay that's results in the formation of a different element?
Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.
